My partner and I stayed at Gary's place for 3 weeks while we visited the UK. The check in process was extremely easy and quick, no issues at all. The place is equipped with everything we needed during our stay, and it's in a great location. It's only about a 15 minute walk to the train station and from there you can easily catch a train to all the tourist attractions. His place is conveniently placed near a grocery store as well as some restaurants.
The space itself was lovely. Its spacious and bright, and it has a nice home feel to it that made us very comfortable instantly. We have nothing bad to say about Gary's place. We thoroughly enjoyed our stayed and we would definitely stay here again if we are ever in the London area.
