It was a nice place, good value for the price (considering that London is a very expensive city!).
Well located with lots of buses nearby, but since it is located South London, you'll take at least 30 min to go anywhere in the City (but I feel that it is the same wherever you are in London, except if you're lucky enough to live right in the center of the city!). We really liked the fact that it is located in a small, quiet and cute street, with lots of trees, away from the noisy main streets of the neighborhood.
The appartment was clean and had good equipments, including towels in the bathroom, dishes, oven and toaster in the kitchen, and good bedding in the bedroom. It was very well heated, which was nice because it was freezing outside in october!
You should know that there is a cat, that apparently used to live in the appartment, that comes back almost everyday. We love cats so no biggie for us, but if you don't, ask for the cat flap in the living room to be closed before you come, otherwise the cat will most certainly come and visit you!
The only big issue we had is that we didn't know that this appartment was rented via Hostmaker. It is a service that takes care of everything, so you never have contact with the real owner and never meet. We wish we had known that before renting the place because we didn't like the fact that you never meet and talk with the owner. We didn't like the fact that you have to go to a store to pick up the keys of the appartment, and in our case we had to call hostmaker because they send a code by email that you have to give to be able to pick up the keys but ours didn't work, so we had to ask for a new one. And once you have the keys, you have to figure out by yourself which key opens what, and nobody welcomes you when you finally arrive at the appartment.
Having to deal with Hostmaker was very impersonal, everytime you need something you have to call them (because they won't answer if you write a message on Air B&B), so you have a different person on the phone everytime. I strongly recommend that you read the whole description of the appartment, which is very complete and useful, so you don't need to call Hostmaker once you're there.
So to sum it up: it is a nice place with everything you need, nice location, cat persons will be happy, and be aware that it is handled by Hostmaker.
