Stefan and heather service is really good, they respond to your questions and needs pretty fast.
We got to a really clean studio , which even surprised us how clean it was , we really enjoyed our time there (we took a 11 night staying) .
Getting to central london was quite a challenge ,but its understandable due to the strikes, still not that of a problem - about 50 minutes instead of 30 to go to the central by a train from richmond station .
Overall a really good place to stay if you are going to london for a long trip like we had for 11 nights.
