I needed somewhere to stay with my seven-year-old daughter in south London for the weekend, and considered a hotel, but I'm glad I opted for air b'n'b instead, because Rose's house is a very modern, homely and spotlessly clean living space of a standard that would compare favourably with most 3-4* hotel suites.
It's a self-contained flat in the basement of a large family home near Wandsworth Common, accessed through the main house, but with your own key so you can come and go as you please.
They ask you not to eat hot food downstairs because of the smell that rises upstairs, but seeing as we were eating out anyway that wasn't a problem, and eating in the family kitchen is also an option as long you arrange with Rose in advance for evening meals.
Rose herself was really friendly and helpful, and although she does ask you to do certain things to help keep the place clean (e.g. not wear shoes indoors, briefly spray the shower with cleaning product after use) that's surely why the place is so clean and well kept.
Wandsworth Common itself is a really nice part of London with a great green space nearby for kids/walks, and although the house itself is on a quiet, well-to-do residential street, Balham is 10 mins walk away as well with lots of pubs, restaurants and a bit of nightlife if you're so inclined. Balham is on the northern line so a tube into the centre of London takes about 35 minutes door-to-door, or quicker still, the overground runs from both Balham and Wandsworth Common, taking 11-15 mins to Victoria.
All told then, this is a cracking little place, good value and highly recommended.
