Sommerro

Rooms and decor

Picture the original 1932 headquarters of Oslo's electric utility, Oslo Lysverker — a rare slice of Art Deco and Functionalism in Northern Europe, with mosaic tile, original oak, and murals by the celebrated Norwegian painter Per Krohg. Then picture roughly 2.5 billion NOK (about US$230 million) spent restoring all of it and reopening the building as Sommerro in late 2022. That's the heart of what makes this hotel unlike anything else in Oslo. The property holds 231 rooms and suites, all designed by London studio GrecoDeco in emerald-green, brass, and warm-wood tones. Open the door to your room and you walk into a slightly Wes-Anderson-meets-1930s atmosphere — deep geometric carpeting, custom brass lamps, and heavy velvet curtains that feel genuinely expensive. The beds get praise across reviews; the green-marble bathrooms keep appearing on Instagram. Many rooms face the inner courtyard for quiet, while higher-floor suites have small balconies looking out over the city rooftops. If you care about design that tells a building's history through every detail, you'll likely fall for the place the moment you walk in.

Food and amenities

If Sommerro has a heart, it's the lineup of 7 restaurants and bars tucked inside one building. Vestkantsalen is the flagship — set under the historic dome where the nearly century-old Per Krohg murals have been restored line by line. Contemporary Nordic food in a room that's grand without feeling stiff. Next door, Izakaya handles Japanese-leaning small plates and cocktails. Ekspedisjonshallen is the basement pub where locals come for beer in low light, and Tak Oslo is the rooftop cocktail bar with city-roof views. Sommerro House Bakery covers breakfast and coffee; Misfornoyde is the casual lounge; and Cinema Bar wraps around the 100-seat in-house theater. Yes — the hotel has its own cinema. Down in the basement is the Vestkantbadet spa, restored from the original Frogner public bathhouse, with white-and-blue 1930s mosaic tile that looks like a film set. Sauna, hammam, treatment rooms. Then comes the headline feature: Oslo's first year-round rooftop pool, heated enough to soak in during a snowfall, with views across the city and a sliver of the fjord. Plenty of reviewers describe taking a swim while snow falls around the rooftop as the single most memorable moment of their Oslo trip.

Location and getting there

Sommerro sits in Frogner, the leafy luxury residential district of Oslo — handsome old apartment blocks, wide tree-lined streets, small cafes and boutiques you can wander all day. The closest must-see is Vigeland Sculpture Park, Gustav Vigeland's vast open-air installation with more than 200 sculptures, a 10-minute walk from the hotel. The Riddervolds plass tram stop (Line 12) is right outside, putting you about 10 minutes from Karl Johans gate, the main pedestrian street that runs past the Royal Palace, and from Aker Brygge and Tjuvholmen, the waterfront district with the Astrup Fearnley Museum and harbor-side restaurants. From Oslo Gardermoen Airport (OSL), the Flytoget express train reaches Oslo S in about 20 minutes; from there it's roughly 15 minutes by tram or taxi — about 45 minutes door-to-door. This location suits anyone who'd rather soak up the residential side of Oslo than stay in the busier tourist core.

Things to know before booking

Straight talk so you can decide. The main trade-off of the location is distance from the Old Town and Aker Brygge waterfront — the places you'll likely spend a lot of sightseeing time. Expect a tram ride or a 15–20-minute walk, which is less appealing in heavy winter snow if you're not used to Oslo winters. Second: pricing. Oslo is already one of Europe's most expensive cities, and the in-house food and drink isn't cheap. Eating at all 7 restaurants will add up fast. Tak Oslo on the rooftop and Ekspedisjonshallen in the basement are particularly hard to book in high season — lock them in the moment you confirm the room or you risk missing out. Third: noise. Some rooms face Sommerrogata street and pick up tram and pedestrian sound in the evening. Light sleepers should specifically ask for a courtyard-facing room. A few reviews also mention that check-in can run slower than expected on peak nights when the hotel is fully booked, and that the famous rooftop pool gets crowded in the evenings — go before 10 AM or after 8 PM if you want it quieter.

Our take

After reading several hundred actual reviews across Agoda, Booking, and TripAdvisor, our take is that Sommerro is the hotel making people fall in love with Oslo in a new way. It's not just nice rooms and good service — it's staying inside a nearly-century-old Art Deco landmark that's been brought back with real craft, combined with a rooftop snow-pool soak, 7 restaurants, an in-house cinema, and a Frogner address that makes you feel less like a tourist and more like someone who actually lives in Oslo. Guest scores of 9.2 on Agoda and 9.3 on Booking, plus three consecutive Best Hotel in Norway wins at the World Travel Awards, confirm this isn't just an opening-buzz blip. Best for couples, design-focused travelers, and anyone who lights up at architecture and history. If your trip is centered tightly on the Old Town and waterfront, you may want to weigh this against a more central choice. On balance we give it 9.2/10 — the boutique luxury hotel we'd most readily recommend in Oslo right now.
