The good things: the location was great - quiet neighbourhood, just two minutes from the tube station, restaurants, bakeries, supermarket and more. Very safe surroundings, fairly quiet. As it is a basement apartment you can hear the underground - we didn't mind so much. Also the check in - the host especially installed a self check in box so we could enter the apartment in the middle of the night.
The bad things: there was a strong mouldy smell in the apartment. The boiler made a lot of noise. And most importantly - on the cold days the heating was not sufficient and we were actually freezing in the room. Also the hot water ended in the middle of the first shower at night, and the next morning there was still no hot water. This was very disappointing and annoying, not to be able to shower normally. The host said he sent someone to fix it but nothing changed. we simply had to take really short showers and not wash our hair sometimes - very very disappointing.
