We were later getting into 1 Narrow Street than we expected, and Marcus and Amy communicated with us nicely to make sure we had access to the keys. The location was very good for us, with a 5 minute walk to the train and easy access to Central London and Greenwich. Good eating within a short walking distance, and not too much traffic along Narrow Street itself, since it is so popular with cyclists. Parking was easy, since the hosts provided permits and we were there on a weekend. We were able to park right outside the front door...excellent!
