The flat was great, very clean and spacious! The area was perfect, very central and covered by 3 main underground lines and accessible by two stations. The neighbourhood is lovely and it is 2 minute walk ti Hyde Park (brownie points for runners). Check in was ok, I had to collect the keys from their office but everything went smoothly.
A small critic is about the shower that runs pretty slowly and the hot and cold water cannot be balanced very well. But apart from that everything went perfectly. I will definitely stay in this place again in the future.
