I spent 2 nights by Vladislav and it was very nice! He was helpful and was there for a late check-in on first day.the room was newly furnished, very clean and light. The only downside, as it was very recently furnished, were the absence of curtains on windows (but I've heard it's common in Czechia) and small lamps next to the bed, only one central light bulb. But Vladislav is ready to make improvements.
The neighbourhood is quite nice, with good restaurants and cafés directly in the street, and trams and metro are close. In the night there is very little traffic and noise.
I recommend for one or 2 people, and there is a 2nd room available in the flat.
Děkuji Vladislav!
