Jack was a very nice and friendly host, welcoming us to his apartment when we arrive and prompt to reply to messages when we had any questions.
The flat was as shown in his pictures, in a nice and safe area.

We did have a couple of issues, but I think mainly relating to the fact that we were the first visitors and came to stay in the apartment before Jack might have been ready: washing machine damaged/not usable, some insects in kitchen (which may just have flow in when the flat was being aired out prior to our stay - middle of summer), and some other amenities not fully ready, and there was no internet (but in all fairness this was as advertised, we had just misunderstood as there being no wifi).
However, Jack was a good host - dealt with us very fairly, and was very prompt to respond with our concerns, so i have no doubt that he will have sorted any issues for the next tenant.
