Highly recommend this stay! Denys was incredibly informative and responsive, telling me exactly what I needed to know ahead of the stay (without even needing to ask). His initial welcome message was a helpful guide as I got to Oslo to understand how to get to his place as well as rules and Wifi information.
The location was incredible! It was right next to a tram stop that we took directly to restaurants, city center, and the Oslo Central Station (extremely convenient with our train travel from the airport and later to Stockholm). It was also very walkable and safe at night. We ended up walking back from some bars and never felt unsafe. It was a quiet and relaxing area, but still very close to tourist attractions and restaurants.
The place itself was also very nice and spacious. It was perfect for our weekend stay, but would've worked for a longer time period as well. The beds were comfortable, the rooms were very stylish, and the tile floors even had heating!
