We stayed in this AirBnB from May 24 - May 27 of 2017. While the unit was large and roomy, we are giving it a three star rating for the following reasons:
1) This is the first AirBnB we've stayed in where we were not greeted and welcomed by the owner or a representative. This has been one of the things we've really enjoyed about AirBnB, but with this unit it was simply a commercial transaction.
2) Hot. I can not imagine this unit in the middle of summer. The days we were in London the temperature was in the upper 70's (25+ C) and with this being a top floor unit it heated up during the day and was stuffy and hot every time we returned from a day of sightseeing. The first day there was no real breeze and with no fans or A/C the unit did not cool down until the sun went down. The other 2 days when we returned we opened all the windows we could, and with breeze it became comfortable after about an hour or so. The lack of fans and air circulation are a negative.
3) Worn fixtures and general lack of maintenance. Mold was actively growing in the shower, broken and missing tiles in the kitchen, and exposed wiring and junction box.
The positives were that the unit was in a good location for catching the Tube, and gave our family plenty of room to spread out. While there were plenty of local eateries within walking distance, we made use of the kitchen and visited Harrod's food area and got some of the "mostly prepared" meals to finish cooking in the kitchen and enjoy a quiet dinner in our home away from home.
