ANEMOLETHE

10/10 Excellent

"The property was beautiful. The morning sunrise view was especially spectacular. Pool was relaxing. Staff was super helpful. Breakfast and all the food was wonderful. We had an amazing time and would definitely return!"

Smaragdi Hotel

10/10 Excellent

"We really enjoyed our stay at this hotel. The room was lovely and had a comfortable bed and a great shower. Everything was very clean. We had our own seating area outside with a small pool to sit in, which was great to come back to after a long walk. Smaragdi is in Artemonas, away from the coast and right next to the main town of Apollonia. Both towns were lovely to have a wander through and there were enough restaurant nearby, although some were just opening up in May. You can walk to Apollonia in about 15 minutes. There is a lovely path through both towns and I would recommend using that as opposed to walking down the road, which we did the first time. There was a map of the area at the bus stop, showing a variety of short walks too. We choose a longer one that we found on Alltrails. The staff were friendly and helpful. Thanks to everyone there for a great stay. Breakfast, which we had included, was fantastic and very substantial. Highly recommend."

Lithos Suites

10/10 Excellent

"We booked a room with private plunge pool and terrace. Room was well furnished and spotlessly clean and having the terrace and pool was great to catch the sun into late afternoon and cool off in the pool. Breakfast choice was incredible with a range of hot and cold lovely food served in a bright room with incredible views. The hotel is only 5 minutes walk from the port, beach and restaurants The staff were all very attentive and friendly, with Fanni in particular extremely helpful with information about the island and places to go . Really enjoyed our stay"

NOS Hotel & Villas

10/10 Excellent

"NOS es maravilloso, las habitaciones y todo en general hermoso, la atención, la comida, de verdad una gran experiencia. Ayuda en todo momento si quieres encontrar una playa cercana que hay tres muy lindas, taxi para ir a las villas o encontrar una masajista, estupendo, me voy agradecida y con ganas de volver."

Boufounis Studios

10/10 Excellent

"My husband and I enjoyed 2.5 days on beautiful Sifnos, and could not have been happier with our stay at Boufounis Studios. Evaggelia welcomed us warmly from the first communication, and greeted us on arrival, providing us with juices and sweets after our travels. We had a beautiful view of the sea and hillside from our room, and could enjoy the scenery and sunshine from our pretty outdoor patio. Though the weather was a bit cool and blustery, we thoroughly enjoyed our stay, and would love to visit again!!"
