The flat was small but it was ok. Sometimes it could be hard to rest on the 1st floor as there is a small sofa, so you need to go directly to the bed. The location is great, very close to metro, bus station and walk distance to Hyde park. We had some back pains in the morning but not sure if it is because of bed or not. Klevio was a new app for us. As a tourist someday we had experience fear of empty battery of our phones. Maybe we are old fashioned on that and we like physical keys. Overall it was a nice flat to choose👍
