Belvedere Hotel

Just had a horrible experience with the Belvedere after a very much looked forward to 6 nights in a panoramic suite.
We entered the suite after we checked in and it’s steaming hot, we thought no big deal of it and reduced the AC temperature to cool it down, an hour later nothing happened.
After a back and forth with reception and even the owner I believe came to check the suite, we were asked to move to a temporary room until it gets fixed.
Went down for dinner at the restaurant and there was no one, when we asked the staff we were told that because the AC is not working inside the restaurant all guests are either in their rooms or out in town. At that point we thought this is not the relaxing holidays we’ve been waiting for, paying for a premium suite at a premium rate and basics are not even met. We told reception that we would leave the next day because our expectations and what was promised on the hotel booking.com page is not met. We told them that we stay in the same temporary room no need to move us to the suite for that one night, but at over 11 pm when we are ready for bed we get called to tell us that suite is now ok. At that point sleepy, frustrated and tired we said no need we will sleep in the temporary room.
Next day we left on the promise that we should coordinate with booking.com to cancel and the hotel would refund.
To our horror a day later, booking.com is telling us that the hotel won’t refund the remaining of our stay. Just outrageous, even after the guy at reception (George) told my husband yes they would.
The booking was not even prepaid or restricted. We left because the hotel failed to provide basic facilities and proper problem handling. Utterly shocked by the way the hotel is handling this, it is just Robbery in broad day light.

Hotel is far from being 4 star, but in reality rather 2 star. Rooms are lacking a proper shower (instead the whole bathroom gets wet) and overall the style of the hotel is rather basic. Some staff is very friendly, but some others were not very helpful.
