If you're looking nice and tidy place, in great communication point (underground nearby), for a fair price - you can stop searching, because you've already found it. :)
Natalia is a great person, I recommend her as a host and her room as a great place to stay in London for couple of days. For sure, we will chose this place, if we decide to visit London again.
Best regards Natailia! :)
