We went there to see the MLB London Games. It was a 30 Minutes walk to Olympia Park. Bow Church Station around the corner, also Busses in every direction (Stansted Airport too). Very kind and friendly people are working there and they are available all the time if you need something. You can get a hairdryer for free if you want. Rooms get cleaned up every day. There are TVs and a perfect running Wifi. Beds are very comfortable and clean.
The kitchen is free to use in the morning and also in the evening. There is everything you need, Coffee, Tea, Fruit, Milk, Eggs, Toast, Crisps, all free to use, a full fittet kitchen with everything you need for cooking and a food store next to it.
It could have been a little bit cleaner and we hat some trouble with the water temperature in the shower at the morning but we enjoyed our stay and come back for London Games 2020
