We stayed in this flat four nights in July. The property manager, John, while very helpful via email in advance of our stay, seemed quite rushed when he met us there to give us the keys. He spent less than than three minutes and uttered two or three generic sentences when showing us the apartment, and then he left abruptly. Maybe he was just having a stressful day - he had seemed so much warmer in his emails, when we had made arrangements to contact him upon our arrival in London.
The flat is located in a reasonably nice neighborhood in Marylebone - there are shops and restaurants nearby, as well as two tube stops within walking distance. It's a little shabbier than the pictures indicate, but it was clean and comfortable enough for our short stay. The beds are very good, and the bathroom has been updated and is quite modern.
As we were unfamiliar with the area, it would have been helpful if there had been some sort of "welcome" folder, as there has always been at the many flats and homes we have rented throughout Europe and the UK. When the manager was there, we asked him where the nearest tube station was, and he gave vague directions, which were useless.
We've stayed in other flats in London over the years, and they have always had some sort of information folders. There was nothing available here other than a single sheet of paper with the internet password on it and information regarding check-out time and where to leave the keys. No neighborhood maps, or information about shops and restaurants, etc. Nothing explaining how the washer and dryer worked (so we didn't even try to use them) or the dishwasher. The first night we were there, the overhead light in the kitchen burned out when we turned it on, so we pretty much only had use of the kitchen when the sun was up. Yes, we probably could have called the manager, but we didn't because he had seemed put out at even having to show us in when we arrived.
This is a nice flat in Marleybone with 2 good sized bedrooms, a well equipped kitchen and a washer/dryer. Very comfortable for myself, my wife and our 19 year old daughter, who had her own room. Marleybone has lots of shops and restaurants and is a reasonable walk to many sites, including the British Museum and Piccadilly Circus. The tube is quite close if you prefer that, and it's easy to catch a cab on Marleybone Rd when needed. The only downside to the apartment is that it's close enough to Marleybone Rd to catch some traffic noise with the windows open, but it never bothered us and frankly big cities are noisy. Very nice and helpful people to work with which is always a plus.
