We have just stayed in John's apartment for 3 nights. When we arrived we had a problem with getting the front door opened. This had been mentioned on other reviews. You need to just stick with it to get the hang of it but it can ce frustrating when you arrive. I did message when we had the problem but got no reply. John did send a message later that evening to see if we had arrived.
Thats where the difficulties end. John's apartment is bright and airy. Very clean. The kitchen is well equipped and the bed is very comfortable.
The location is perfect and everything you would like to see in this beautiful city is within walking distance.
I would recommend John's apartment to all guests. Just be patient with the door .
