We had a great stay at Jonty's. The flat was cool, really tidy and had everything we needed for our stay. It was close to the tube too which was very handy as we were working in central London.
Jonty was a lovely host, he was available for any questions we had.
Check in/out was super easy too.
Our only negative about our stay was on the 3rd day while we were out at work, the person who lives in the flat below used a spare set of keys and entered the flat we were staying in. We were not notified about this and we felt it wasn't ok for a stranger to enter the space we were staying. We would always allow the host or someone else to enter the property for whatever reason they needed to, however I think it is not a lot to ask of the host to let guests know if this is happening. Due to our work we had a lot of expensive equipment with us and didn't feel safe with it in the flat because we spent the remainder of our stay always wondering if the person from the flat below was going to come in again unannounced.
Other than that we had a great stay, thanks again.
