Because WiFi is important to us (besides the usual things), I asked the hotel management one month (!) in advance of booking whether the problems mentioned on the net regarding the WiFi, were solved. The manager assured us that they were working on it, and that the problems would be solved in the coming days. After that, I booked a room for 5 days, pre-paid, about Euro 1000. In the first room we got, the WiFi did not work (my laptop is first class) and in the second room there was WiFi for just one evening. We did not accept a third room, because that was totally not like the one we had booked. So, I was sitting in the corridor, next to the elevator, every time I wanted to have WiFi receipt.
I tried to found out what was wrong (too weak transmitters, thick walls, and such). Also, I found a damaged antenna, close to us. All the time the management assured me that I had signal and WiFi, ignoring the problem. They were arguing with me constantly, whereas the hotel engineer fully agreed with my findings. At one time a WiFi-amplifier was plugged in, in the room, but there was nothing to amplify.
Now I write because Denise from Belgium, at the end of July 2019, has experienced the same matters with the WiFi as we have. So, nothing has changed. Also, she writes that there was a problem with the cook(s) for the evening restaurant. That was already the case in the beginning of June (!) 2019. During the day/lunch time, there was no food available at all, although a lunch menu was advertised outside. At check-out time, not a tiny compensation for the problems we encounted, was granted.
Back home, I wrote a constructive mail to the owner of the hotel, explaining what measures should be taken to come to an acceptable WiFi-system. I got a nasty letter back, again ignoring the problem.
The breakfast was great and the ladies serving it were very kind. The room was nice, as shown on the net and the location of the hotel is good. When you go to this hotel and you want WiFi, be prepared to sit aside the small reception or in the corridor outside your room (for 200 Euro per day); you will see other guests walking around, carrying their open laptop, seeking WiFi receipt. My strong advice is, when you want to go to this hotel: avoid any discussion and confrontation with the management or the owner about any topic whatsoever!
