We really enjoyed our stay here! The location was amazing, just a few minutes walk from kensington garden and hyde park, a couple minutes from the tube and round the corner from great shops and restaurants.
The room was fine for what we needed it for, it could probably benefit from a lick of paint but was overall pretty clean. I personally feel that the room could benefit from a full length mirror as opposed to just one above the sink in the bathroom, considering the kind of guests I imagine would stay here.
The keyless checking in system was great but did make me worry about making sure my phone didnt run out battery. Also the room we stayed in had an iffy catch on the door, so when leaving to go out you had to make sure it was positioned just right otherwise the door would either not shut or would be able to be opened again straight away without using the app to unlock it, so this is definitely something to check.
Communication from max and billie was great, really helpful in explaining how the keyless system works, and were really quick to let us know about emergency water works, which luckily didn't effect us as we were out at the time.
We would definitely consider staying here again :)
