Vincent's place is awesome and we loved staying there.

(1) We had not used airbnb before as we were concerned about the quality of service but we had an amazing experience staying at Vincent's apartment and that changed our perception completely towards airbnb.
(2) The room was better and bigger than what it looks in the photos!
(3) The room is right next to Namesti Republiky, a major central square in Prague and is easily walkable from everywhere in central Prague.
(4) Vincent's directions to the apartment were crystal clear and his book describing things to do and places/restaurants/groceries nearby was very helpful. The room also had guidebooks for Prague and a Czech to English dictionary.
(5) We were only two but the room can comfortably host three and maybe also four people.
(6) Vincent was staying in the room next door and promptly responded to all our queries and also provided us with an electrical converter.
(7) The room has a lock and key.
(8) The bathroom in the room had all essential toiletries - body wash, shampoos, hand soap etc available. As mentioned in Vincent's description, the bathroom in the room is for shower and the toilet is in the living room.
(9) The room has a water boiler to make coffee and a microwave. The living room has a fridge, oven and stove if you want to cook although there are so many restaurants around that we just used the kitchen stuff for coffee in the morning.

We would definitely return and stay at this apartment.
