This hotel is brilliantly located in the old town, everything is walkable and convenient. The staff were very helpful and always friendly, the breakfast was ok, simple but nice. The hotel itself is a bit dated and could do with some modernizing, but worked well for our family as the family suites can accommodate 4 people in two separate rooms.

The hotel is clean and well-maintained, and the staff are incredibly helpful and make you feel right at home. The only downside is no parking. Overall , a great choice and highly recommended!

Best hotel I have ever been to in the world!
I, James, vouch for this hotel. This is the best hotel I have ever been to in the world. Let me elaborate – I have been all around the world and stay in 5-star hotels all the time. Yet this hotel is the best one I have ever been too. Yes the location is great, the breakfast was good, the room was awesome. The competitive advantage and key differentiator for me, was the customer service and support. I am talking about 100 out of ten stars. They always went the extra mile. They answered all of my inquiries about local areas, and gave me personal – I mean personal recommendations because they leveraged their personal network to help me. For instance, I was deftly afraid that I was going to get scammed, but they got me a taxi driver of whom they trusted and everything went so smoothly. Another instance: at the airport I got a little confused because of the updated policy. I reached out to them for assistance and they went above and beyond and contacted someone at the airport to help me personally. Another instance: When I went up to the terrace to simply enjoy the view, Mr. Huseyin was kind enough to bring me some Turkish tea to enjoy. After I checked out, and even after I stayed for only 4 nights, I genuinely felt like I was departing from friends who took such good care of me. A few days after I checked out and was at a different location, I wanted a Turkish local to verify something. The staff at this people helped me - even though I was no longer a guest! Thanks to the staff!
