Per Lexi, the actual guest: Absolutely great location and particularly good price. Right by Green Park station and well-connected to all of London and environs. Everything needed in a compact space (think: Manhattan studio x RV living). Yes, the size is small, but really, who needs more than a bed, bathroom, and microwave/electric kettle when touring London? The only thing that could be suggested is a small electic fan, when taking into account the recent hot London weather.
Julio was a pleasure to deal with, easy check-in and very responsive to all queries.
