My wife and I stayed at Att | Kvadraturen for four nights (Suite) in August 2025. We absolutely loved this place, and it is one of our very favourites out of the hundreds of hotels we have stayed at over the years. The Apt was very spacious, well-designed, very modern, spotless, comfortable and had everything we needed. Camilla and Elin met us upon arrival; they were very friendly, professional and helpful throughout our stay. The location is perfect, right in the heart of all of Oslo’s main attractions, surrounded by some wonderful cafes and restaurants. They don’t clean every day, but you have access to clean towels and other supplies in a supply room (I prefer this arrangement). We also appreciated the washing machine and dryer as we are on a long trip. Opening doors by app was also really cool. Wonderful place!
