Great, safe & secure location. Do not expect luxury accommodation and you would be fine. Place is very convenient to walk to attractions or tube as per your preference. Room(s) are not tiny (as happens often in Central London); kitchen is tiny (we had not planned to use it). Overall building is in a quiet location but I could hear other tenants from the bedroom (thankfully they were very brief conversations). So in total a great place for a small family / group but open to quibble if you are so inclined :)
I should also add that the host mailed out couple of items (that I had forgotten) the very next day - I appreciate him going out of his way. Thank you.
