I spent 3 nights at Joanna's place and I had a really nice time. She is a kind and flexible host and gave me great tips what to see and try out during my stay.
The flat is in a nice and quiet neighbourhood, the bus stops are like 2 minutes away so you can easily get to anywhere in the city. There are cafés and shops nearby as well as some beautiful parks you must visit.
The room (and the whole flat) is really stylish and clean, I loved all the art and the creative decor! I'd definitely choose to stay here again in the future!
