This is a perfectly situated flat for visiting all the sites of Prague. The public transport system is great and the trams leave right out front. The flat could have been cleaner. There is also a lot of street noise and also light coming from street lights and a brightly-lit advertising board. The kitchen could have more cooking equipment. And the stairs were a bit much for us...
But if you don't want to eat in and you party most of the night and you have the legs for 3 flights of stairs, then it is a nice flat in a good location.
