Where to even begin with this amazing stay? Andrew (Andy) was a fantastic host. He was communicative, flexible, accommodating, and genuinely sweet. He left some food and drinks in the flat and were kind enough to tell us to help ourselves. The flat was comfortable, well-appointed, and quite conveniently located.
Location, location, location! The flat is a 5 minute (or less!) walk from two underground stations servicing 4 lines between them. Getting anywhere in London is a breeze. There are several cafes steps from the door (including a Pret) and the neighborhood is surprisingly low-key in the evening.
The flat itself is great: the best of a home and a hotel in one place. Amenities include (but aren't limited to): an iron/ironing board; a nice hair dryer; a washing machine; and several drying racks, including a heated one. The decor is warm and modern. The bathroom is gorgeous! There is also a concierge at the front desk during the week until late, and sometimes even on the weekend.
Check-in and check-out were easy: we met Andy at the flat to drop our bags and get the keys when we arrived. We dropped the keys through the mail slot when it was time to leave. That was it.
