This place has many things going for it. Very clean . . . Extremely easy to check in with instructions on how to use the keypad outside the door . . . Very good location for seeing a ton of sites and very convenient to the Embankment tube stop but also a few other tube stops that are a short walk away (Charring Cross and Westminister).
The apartment was very clean too and a great layout. The host was very communicative and responds well to questions. WiFi also was easy and worked well.
The one downside for me (and I recognize it won’t be a downside for everyone) is that there is a night club or something close by where it can be fairly noisy with people outside until about 4am during the “prime going out days” (Thursday, Friday, Saturday which happens to be when I stayed there - which is why I rated this place 4 instead of 5 stars). Sleeping can be a little harder if you are a light sleeper.
Other than that, this is a great little place with a very nice host and good location for walking London.
