I rented Sean's loft for my parents, who stayed in London for 4 days.
Pictures and description provided clearly describe Sean's loft.
The host was not in London at the time, but communication with him was smooth and he was very nice and friendly.
Small but comfortable, quiet, nicely decorated space. Good value for money. Kitchen appliance is basic. The room can get hot when temperatures are high but a dehumidifier is provided.
The place is located in a nice area; shops of any sort are located at walking distance, as well as beautiful Broomfield Park. The house is in outer London, but well connected to central London. Palmers Green station is the closest, while tube stations (Arnos Grove and Bounds Green - Piccadilly line) are a 10min bus ride away.
