There are pros and cons. I stayed in two flats in the building. Both were very clean and comfortably furnished. The staff (manager, cleaner, maintenance) were all very helpful and responded very quickly when issues arose.,
Unfortunately, there were some problems with apartments and the building itself, such as broken appliances, incredibly thin walls, broken elevators. If you’re noise sensitive and/or in London to work, this may not be the place for you. (Staff we’re really helpful in dealing with various problems but it was still a bit time-consuming).
The building is safe though (with staff on duty 24-hours) and the location is fantastic.
