Great location and responsive hosts. The apartment was warm in February, felt bright and airy, and there was loads of hot water for 2 people.
I was traveling light, but guests with large suitcases will have to contend with the typical staircases found in these types of buildings. Similarly, the soundproofing was extremely poor but that didn't bother me because the other occupants and street noise were both very quiet.
The flat had great internet and the hosts left a welcome booklet with lots of great suggestions.
