We stayed at David's apartment for 3 nights. David was very prompt with communication and super friendly.
The apartment is very well located. 10 minutes walk from Big Ben and West Minster metro station. Walking distance also from the South Bank. There is bus stop in the beginning of the street. You can take the bus directly to Trafalgar Square, and walk to west end and Soho area.
The apartment is well equipped. We had a very pleasant stay. Highly recommended.
