Petr is very nice, it was a good experience staying with him.
The room was very spacious, more than enough place for one person.
The apartment is on the third floor so you have to use the stairs(no lift). The location is around 20-30 minutes using public transportation to all major tourist attractions. The area is clean, safe and I felt good staying there.
I loved the fact I could use the home computer, I really needed it.
I really believe you won't find anything better for the price!
