I had an issue with Jay because I had to cancel my renting. As I am staying indefinitely in Berlin, I was always on the look out for a more permanent stay. Thanks to my work network, I found a good deal pretty quickly. When I said that to Jay he changed.
I had to constantly get back to him as he didn't answer my calls and messages. It was like trying to deal with someone's tantrum.
At the end I was quite direct with him, telling him I paid 4700e for 22 days of renting and he got it pretty good even if I didn't stay all my booking time.
The fact that I paid that much and still got to reassure him to get info I needed should tell you more about the issue here. It's not professional. You don't do a 360 in your attitude just because things didn't go the way you wanted them to go.
So after reading all the reviews here I was quite disappointed. There were less expensive apartment but I chose this one because I thought Jay was amazing, but I wouldn't advise anyone to do the same.
