"Location is perfect, steps from the water where you can swim. Just a few minutes from the local buses that can take you to Chora (top of the island) and different buses that can take you to popular beaches like Agios Sostis and Psili Ammos. The staff was great , check in was easy , good space inside , great value!"

10/10 Excellent
"From the moment we arrived the staff were incredibly helpful, giving us tips about the island and showing us the hotel property. The property itself was very clean and the rooms were cute and very usable in terms of their layout. The breakfast was a standout hit. The only note I would make is that the parking is quite small, which is not uncommon in the area but just so people are aware that if they have a larger rental car, that can be tricky we had no problem with our little hatchback"
