No frill accommodation that is situated at a very reasonable walking distance from Excel - not more than 15 minutes walking even on heels! Great value for price. Very clean place.
Plan for coffee, breakfast and all dining activities outside as there is access only to sleeping quarters and bathroom - ideal for those going to a conference at Excel. Beware there is nothing much in terms of eateries close by.
Easiest way to get into central London is to walk to Customs House (so about 10-12 minutes) where you have the Elizabeth line and DLR. If you need your morning fix there is a Starbucks right by the station.
