Two of us stayed here for a week in July. It was quite hot so we had to sleep with the window open so fairly noisy on the second floor. Ok if you are used to city noise.
The tram service into town is excellent and the stop is only 100m from the door. 24Ck for a single trip or 110Ck for a day pass but free if you are over 70! Buy the ticket from the vending machine on the street corner by the stop then validate it on the tram by sticking it in the yellow machine, alternatively buy the ticket on the tram using a card at the orange coloured machine.
Cooking facilities are fairly basic but there are several reasonable eating places near by so you probably won’t want to cook in the flat.
The bed was comfortable but the armchair and sofa could better be described as adequate.
The bath was good with plenty of hot water but the shower was a hand held unit with no curtain so not really possible to stand up to shower.
Parking on the street is free and we always found somewhere close by. The brand new hire car was not damaged and it seems to be a fairly safe area.
We would be happy to stay here again if we visit Prague in future.
