I stayed here in Lex's BnB for 5 nights. My experience was excellent. The house is clean, comfortable and centrally located. There is a fairly large Tesco 1 minute away from the property and therefore you will have access to almost everything in no time.
Also would like to highlight that Lex is a great host. He is always up for a chat and has a variety of interests. He is extremely helpful and is very adjusting.
If you are in London and plan to stay in a nice, centrally located clean accommodation with all amenities, go for this one. It's worth each penny!
