The In-House Experience
At Solli Plass, in the Frogner district, Sommerro is part of a location that already carries urban memory. The original building dates back to 1930.
The in-house experience is rooted in this embraced continuity. The architecture does not seek isolated effects; rather, it engages in repetition, adjustment, and presence.
The renovation carried out in 2022 by LPO builds upon this historical foundation, with a careful reading of the existing structure. The contemporary gesture complements the space without overshadowing it.
This transformation was conducted in close collaboration with the international studio GrecoDeco, as well as with the owners Aspelin Ramm and Strawberry Brothers. The result is a coherent composition, conceived through multiple voices.
One can perceive an architecture of dialogue. The building retains its 1930 roots while adopting a renewed expression. This measured tension shapes the stay.
The feeling of being at home arises from this. To inhabit Sommerro is to enter a place where renovation does not interrupt history; it methodically extends it, in a readable and serene architectural language.
Dining
The dining options are the most well-established aspect of the hotel. Michelin Guide recognises Plah within Sommerro, Oslo, presenting it as a Thai restaurant.
The concept revolves around Norwegian ingredients infused with Thai flavours, centred around an open kitchen.
The Michelin Guide also mentions Ahaan, a venue inspired by Bangkok's street food scene. Both restaurants are located within the Sommerro Hotel, operating independently.
Wellness & Spa
The Sommerro spa extends the spirit of the venue with a straightforward and accessible approach to wellness. Here, the experience is built around a few essential elements.
The rooftop pool adds a unique dimension to relaxation. Elevated, time seems to slow down. The light, air, and views of Oslo naturally accompany the moment.
The sauna complements this setting seamlessly, providing the sought-after contrast between enveloping warmth and deep relaxation. Its use remains timeless, almost ritualistic, perfectly suited for an urban day.
The overall atmosphere prioritises a form of wellness that is unpretentious. There is nothing ostentatious, but rather a carefully designed environment to rediscover calm, catch one’s breath, and distance oneself from the city for a few hours.
For a stay in Oslo, this spa thus offers a clear refuge, perched above the daily rhythm. It is a place where one comes as much for the serenity of the space as for the quality of rest it inspires.
