Piotr'a house was great value for money in East London and nice and close to public transport connections.
When we stayed it was very warm. There wasn't any fan available and with the windows open it was too loud as the property backs on to the main road. This made sleeping pretty difficult! Also, unfortunately on our first night of the stay in the early hours two people came home and were talking pretty loudly in the room next door.
I wouldn't say the house was overly clean but Piotr and his girlfriend were lovely and did make us feel welcome.
