Barnes is a great location to stay if you are visiting London. It has a village-like feel with its duck pond and independent shops, including several mini-supermarkets. There are four bus routes up to Hammersmith where you can catch the tube straight into London or out to Heathrow.
Eve's place is in a quiet mews. The main bedroom has a double bed, and the second bedroom has two singles (one bed with a pull-out trundle bed underneath). The living room downstairs has a sofa-bed with a very quick & easy mechanism to convert it for sleeping 2 adults or kids. There's a full kitchen with good appliances.
The house is warm, and the bathroom clean and bright. The host, Eve, doesn't live too far away and was always on hand if we needed anything without being intrusive.
We stayed as a family of five. Two adults, and children aged 15, 13 and 10. There was plenty of space for us, cheaper than staying in a youth hostel, and much nicer. We'll certainly return next time we come.
Highly recommended.
