My sister and I stayed at Patricia's house for about 2 weeks and it was a very pleasant and wonderful stay. Patricia was a great host. She made us feel like we were at home, she kindly allowed us to use the living room/kitchen/washer/etc, and we had some good conversations. She gave us good advice on where to go around in London.
The room was nice and spacious, perfectly suitable for two people.
The location is also great, around 5 minutes by walk from the underground Kilburn station. The jubilee line will take you to almost anywhere in central London (ex. Victoria, Soho, Westminster, even Greenwich). There are also some buses right in front taking you to places like Oxford street. Plus there is Sainsbury's and Tesco nearby to take care of your groceries.
We really enjoyed our stay here and recommend it to other guests as well :)
