Nice, comfortable flat, convenient to several stations and the bus. Lots of decent food options nearby. British museum is about 1 mile or so away (walkable). Soho and Theater district are a bit farther - can walk or take bus. King’s Cross Station is fairly close as well. Easy to get to all the main attractions by bus or train. Medium sized market is about 10 min walk.
The double bed and sofa bed were comfortable. Kitchen is decently equipped (even had liquor which we didn’t touch). Bathroom was clean. Shower was fine. Elevator is convenient as the flat is on the 4th floor. Lots of windows can be opened to let in fresh air. We didn’t use the washer but the flat has one. There is a small balcony overlooking the gardens (each unit seems to have a plot).
It’s a bit inconvenient to get to Mornington Crescent station by the tube with luggage (lots of station transfers, not all have lifts or escalators). You have to pick up the keys at a convenience store near the station, but that worked out ok. There is a tasty restaurant near there called Alexander the Great (food from Cyprus) which we found on the last night.
Camden markets is nearby. There is plenty to do, and this flat was conveniently located to explore London. We would stay there again.
