We were very happy with our stay in Bellas very good equipped house. The location is great, very close to a tube station, bars, restaurants, nice cafes (Bridge Cafe - very british breakfast :-)). The room was perfect for us - nice bed with a pleasant bedding, spacious shower and the price is very fair!
Bella itself is a perfect host. Communication was easy and very quick, she is friendly and helpful. We had lovely 4 days, that's why it's our recommendation if you want to stay for a couple of days in London!
