I had an excellent stay at Ilgi’s place! The room was very comfortable, and with a small desk was great to either relax or get some work done in the evening. The location is about 30 minutes from central London by subway (8 minutes walk to either Wanstead or Snaresbrook), which is very convenient on the Central Line which has a station walkable to most London sights and attractions. The Wanstead neighborhood is really nice, with some good restaurants just a minute walk, and coffee shops, pharmacies, grocery stores, and a park within five minutes walk. (If following an app for maps, it might suggest getting off at Snaresbrook, but I recommend Wanstead - the walk is about one minute longer, but goes past a nice street with shops and restaurants; Snaresbrook is nice too though with a walk down residential streets - trains to both stops are frequent and you can take whichever one comes first.)
Overall, this was a great place to stay for London!
