Irina and Natalia's flat is a really great location, it 's what i expected from the photos and the descrption,no problem for the check-in/check-out time and Irina was very helpful with us.
The location is linked to the city center by metro(the metro stop is just 2 minuts walking from the flat)but it's also easy to get it on foot(10 minuts walking), futhermore Irina speaks a very fluent english so we didn't have any problem to talk with her.
I can only say thanks to Irina for the beatiful holydays which we passed in Prague.
Best Regards
