If you’re in London for sightseeing and just plan on using this apartment as a place to sleep, it is probably one of the best you can get. This is mainly because you can get everywhere on foot easily.
The flat itself is very clean and everything that was promised was there and worked fine for us. Communication with Maggie and Lawrence was easy and much faster than we expected.
The only things you have to watch out for is that the bed is extremely soft to the point where you might get serious back pain from sleeping there for multiple days if you are very sensitive. Also keep in mind that everything (especially the bath) is really small and you don’t have much space anywhere.
All in all this apartment is excellent for if you want to do general sightseeing because of the the location but for everything else I probably wouldn’t recommend it.
