The suite was great, it had everything that you would need for a stay.
The Thames Ditton location has parking at the rear, but is severely limited in that there are what appears to be a couple of storage containers, removing the additional spaces they are sitting over. There were a couple of times where I parked across the street in a public parking lot, but rates there were good also.
The keys you receive, yes physical keys for both the main front entrance and the room only unlock those doors, not the rear entrance from car park. That entrance is hidden by the storage containers, and is without any signage to point you in the right direction. We arrived at night, there is no rear lighting in the carpark, while it is a gated area, the light issue would be an issue for some.
The suite that I had has two bedrooms, and all doors could be locked.
The building (older facility) has 3 floors and no lift. So you do get a little workout, but be aware.
The check-in was easy, but at their hotel which is very short distance away on the same main road.
I would stay there again for sure! The overall experience was good, 8/10
