The best thing about this place is its location: it is very central with easy access to trains, underground, buses, and plenty of cafes, restaurants, bars, and shops in the Victoria area.
Despite being in a central location, it is also extremely quiet during the night. Until the end of August 2019 there is some building work being done nearby during the (week-)day, which was noisy. I expect that once that building work is finished it is also very quiet during the day.
During our stay (early August) the weather was fairly hot, and the flat can get a little too warm both during the day and at night, especially the top floor where the bedroom is.
Communication was always very quick (always less than ten minutes) and pleasant. Both check-in and check-out were very smooth with no problems.
