Arek has been a friendly und helpful host. There have been some problems with the apartment, but he organized quickly a very nice alternative which I could choose myself from several suggestions. I can't say anything about this flat here. But I stayed in another one which was super nice located, furnished very tasteful and equipped with all you need (so my rating above is for the one I lived in). Arek and his sister have been very flexible with check in and check out times. The key transfer was completely uncomplicated. The have been super kind and offered us help regarding activities in the city.
In summary this has been the perfect experience that you wish for!
Thx
