There are a lot of good things to say about this apartment: The bedrooms are spacious with a walk-in closet and a vibrant color scheme. The hosts's paintings are also really interesting and refreshing. The place is recently renovated and pretty well cleaned, apart from a few exceptions. The location is excellent, and the host is very friendly and communicative.
Unfortunately, there were a number of things that left a mark on our overall experience: The matresses were of low quality with no firmness or shape, so we had constant back pain while we were there. Plus, there was construction going on in the apartment next door, so we were woken up by banging and the walls shaking early in the morning. The bedrooms have heating that works well, but the bathroom doesn't, so it was really cold there. The kitchen has pots and pans, but they are dirty, scratched and bent out of shape. Random other things were also broken and in need of repair (kettle, shower head).
So, all in all, it could have been a great stay, but ended up a mixed bag.
