Basically the appartment was as it is explained.
The welcome was great, Rena provided a self-made cake, and a dish with cheese, olives and bread. Also some groceries for the start were provided.
I was always able to reach Rena during the stay and she gave hints what and were to visit.
Warm water was not available for 24 hours (not in the morning and on cloudy days)and WIFI didn't work stable. Also the knifes were of a bad quality, I had to buy some on my own for cooking. At the end she wanted me to pay 60€ for scratches on a table, and I payed that.
Summing up, almost everything was great, I really recommend the stay there!
