Luis and Ricardo's place is nice and clean, and they are very welcoming. Usually there are several people staying there, but there are plenty of bathrooms, so it wasn't a problem for us. The location is very convenient, about 10 minutes walking distance from King's Cross. In case you are easily bothered by noise, keep in mind that you can hear subway trains every few minutes from inside the house. The noise is not loud, it's more of a background thing.
