Mark was really helpful and nice since i first sent the request. He was very fast answering questions and making our lives easier in London.
The apartment is almost next to the "Russell Square" station and very central. There is a shopping centre behind the apartment, 24 hrs open markets (including Tesco express).
Apartment is very clean (as it gets cleaned before you get there), enough to accomodate for 5 people (Couch for the 5th one). It has a view of the shopping area and cafes, and is very bright. The building may look creepy as it has a very long corridor but is very safe.
Do not hesitate to arrange it, amenities are great, very central, very bright, close to anything you need, and a nice landlord
