Vicent's appartment is in the centre of old town in Prague. You can walk almost everywhere in the centre so only buy single metro-tickets.
The bathroom and kitchen are shared with other people, but that was no problem at all. Everything was clean, towels are offered, you have a place in the fridge where you can put your stuff. Moreover, Vincent has a book with advices what you can/should do in prague. This was very helpful for us.
So if you plan to travel to Prague and want to walk around in the centre of Prague, this appartment is a very good place to stay.
