My wife and I stayed at the "Salo de Circulo" room. It's just like in the photos, or even better. Plenty of storage place, very nice lamps and lights, and even a very well located desk for writing, ironing, etc. The room has also a very comfortable sofa. If you like little details in decoration, this is the perfect place to stay. The living room is very nice as well, it's big and perfect for watching tv, playing the guitar or working on the computer. You can use it any time. The kitchen is another "social space" where there is a very nice table with three chairs, perfect for lunch or dinner. And it has all the things you need to cook, specially if you like to cook. And if you don't, there are two ovens / microwaves. Everything is very tidy and clean.
The location is great. It's in between two streets with lots of buses and trains (underground, overground and DLR). You can get there in less than 10 minutes walking.
About the human factor, Keith was very kind and helpful. If you have a problem, he does everything he can to help you out. He is very polite and your interaction with him is as much or as little as you want. During a cup of tea or two, he can tell you very interesting and/or amazing stories about the city or about the British culture, which is great specially if you come as a tourist or if you are planning to settle down in London. Keith's daughter is lovely, and her Spanish is very good.
If you want to feel at home, we definitively recommend Keith's place.
