Patrick is a super friendly, open-minded host who makes you really feel at home in Greenwich. There's even tea for you.
The room is certainly small (as advertised) but the location is one of the best you can get. Walk to Greenwich's main attractions - you don't even need to take a bus.
Moreover, there are several supermarkets and pubs as well as the DLR station within walking distance.
When I go to Greenwich next time, I'll certainly try to book the room again.
