The apartment is lovely, located on the 7th floor of an elevator building in a convenient location near Marble Arch. Communication with Sam was smooth, and one of his associates met me at the apartment for check-in. The apartment is clean and had plenty of towels and linens. It was a bit loud as there is construction across the street and you can hear lots of street noise, but being from New York this was not a problem :)
The bedrooms felt a little dated and had old mattresses, but we still found them to be suitable. The door knobs are not attached for a couple of the doors, but that seems like an easy fix. The small shower was a little tricky, but again, everything was sufficient and it was a good value for having 8 people sleep comfortably and the kitchen/living room area being very clean and lovely. Would recommend.
