My wife and me, 63 and 67 stayed three nights in Dominik's appartment. It is a good and very quiet place in Prague. You will not hear any traffic or streetnoise at night nor day. The appartment is very clean. We could prepare meals, everything we needed cor cooking was in the kitchen.
Dominik is a nice host likes to give tips about sights in Prague, not only the obvious, but also less known places.
We can recommend this place. For public transport to the city you need to take the tram and change to metro after three stops. The tramway stop is a few streets downhill. That means that when you come back you must climb the hill but that is quite easy if you are in normal condition.
