In general, it was a really pleasant stay. Tomasz was welcoming upon our arrival and helped us a lot with some good tips to the city.
The apartment has several rooms, all of which are rented out so you almost get a hostel feeling when staying there.
Just some few con comments:
1. The bed was unfortunately not too good - you almost fall out of the bed as the mattress has become very uneven.
2. There was SO much noise from what we believe next door until late frem Wednesday to Sunday. It really affected the sleep quality. Not even ear-plugs worked :(
3. The room was too cold.
4. The WIFI was slow.
