We stayed for 6 nights, 2 adults and 2 teenagers. The flat was clean, the location was great as we were near the center and the train stations (St-Pancras and Euston), the neighbourhood was quiet and the communication with Peter went well.
One of the bed was king size, but the second one, a convertible sofa, was too small for 2 people. Take some earplugs because the waste collection lorry comes every morning at 6.
