Great localisation - 50 meters from Main Square. Apartment is really nice, cozy and very clean - well equipped kitchen, quite nice bathroom and comfortable bedroom.
Only issue we had was about noisy nights - but we were in Prague during holidays, in a weekend - and since apartment is placed so close to Main Square, lot's off people walked nearby even at 2AM in the morning. But this is really very small disadvantage comparing to great localisation, modern rooms and helpful host.
We really consider to visit this place again next year.
