Hotels near Monastery of the Annunciation of Theotokos

"Sad to say the hotel stay was substandard. We booked two nights hoping for a solid 4 star hotel as advertised. We got a room and noticed some mold on the AC. When we asked to leave and get our money back, we were refused. We deiced to stay. Once we looked closer the mold turned out to be much worse than originally thought. Bathroom was affected by mold too and the visible parts of drain pipes were very dirty. It was fifty beyond what words could describe. See photos attached (if possible, I want to include these. I did provide the photos to Expedia for their review). Next morning we asked to leave again and get our money back. Again refused by the hotel. We were told that the hotel could only offer us a different room. We told the staff that even if we are given a different room for a second night, we feel that our health was compromised by staying at the room that first night. We did not want to risk any further and decided to leave the hotel, although no refund was offered for the room. We were honestly amazed at how unwilling the hotel staff and management was to do anything meaning about the matter. Expedia also tried to get them to agree to give us a refund considering our experience with the room and the mold. Expedia was very good and supportive in so many ways, unlike the hotel. Please make your own conclusions if you desire to stay at a hotel like this. My wish is that the Greek authorities would also be aware of what this “four” star hotel is offering their guests "
