We loved our stay here! We were here for a little over two weeks and it was extremely comfortable the entire time. The room and bathroom and EXACTLY as pictured, it is clean, homely and overall a very pleasant place to stay.
It is also pretty close to both the Kensal Rise and Kensal Green stations (like a 7 minute walk to each), and there are enough stores within a two or three block radius to make little trips for coffee of toiletries very easy.
Also, Katherine is wonderful. She is very welcoming and nice, consistently made sure we had everything we needed and communicated extremely well both before and during the trip!
I would highly recommend this place -- it felt like a home while offering plenty of privacy. The next time I come to London this will be the place I stay if it is available!
