The AirBNB user is Tomas, the person that contacted us was Petr, who was supposed to pick us up from the airport for a price and he instead sent his son. We contacted Petr 2 hours before arriving, and he didn't mention anything about it. Petr's son was nice and dropped us in front of the building, provided the keys and left. When we arrived the light of the apartment was fully shut down, but we managed to sort it out.

I fully reviewed the description of the host and couldn't find anything about the disgusting odour and noise that comes from the back of the HOTEL ROTT's rubbish backyard. The backyard is above and in front of the corridor, where the toilet is, and connects the main entrance to the kitchen. Every night they woke all up because of the noise they made up to 2 or 3 am.
The toilet didn't have any ventilation, add the smelt rubbish backyard and you might have an idea of the first thing you will appreciate when entering the apartment. Whats more, when people staying in the bedroom require to use the toilet, they will have to traverse both the living room and the kitchen to use it, and then use the sinks in the kitchen, because there is none in the toilet room.

The bathtub drain gets clogged every time you used and there was no mope to clean the water coming out of the drain after someone took a bath.
Bed sheets (essentials) were not provided for the double bed in the kitchen.

Apart from all these, the location is exactly as described, in the centre of the old Prague.
Don't get me wrong, Petr and his son were nice enough to provide an average service, but many misleading, uninformed or unattended things affected our experience, noteworthy our time and quality of sleep.
