The apartment was in great location, a few metres from Marylebone station, and a few minutes from Baker street Station. Very quiet apartment, the street wasn't noisy at all. It had everything we needed for cooking, bath and sleeping.
Since we are from Spain and are used to blinds and things like that, we would have appreciated thick curtains, although it wasn't big problem in the end. But all in all, if we ever come back to London again, we will stay in the same apartment, for sure.
