Katja's room is very comfortable and clean. The apartment is super cute in general and the kitchen and bathroom are well equipped with everything necessary, a boiling pot, coffee machine, all pots and pans (we cooked so we checked).
Katja was a great host and available for communication and very helpful around everything we needed help for.
The neighborhood is also very, very good, the street itself is very vibrant with beautiful breakfast places, bars, stores and young spirit, yet it's quiet enough so that you can have a quiet night in if you wish for that.
There is a tram station less than minute walk away and the location is wonderful.
All in all, we had a great experience with Katja and I would completely recommend staying in her beautiful room and apartment!
