"First of all, Kostas our host was a gem. His English is limited but that’s part of traveling, right? The room was clean and ready on our arrival and the bathroom had clearly been updated very recently. It had all the basics needed. The view from our outdoor terrace was idyllic. Expect stairs in and out of the property—a lot of them. As soon as Kostas saw us struggling with our bags, he jumped in to help and offered to help on our last day back to the port. It would be great to have a shade on...

Voya Sifnos Mindful Stay

10/10 Excellent

"Voya is a very rare, special boutique hotel. The setting looking over the Kamares Bay is exquisite & the staff (especially 'Jack of All Trades' George) is personable, helpful and dedicated to their guests. George went above and beyond and made our stay incredible...a true gem! The property is gorgeous and the the fixtures in the room are top notch. The small number of rooms are all a bit different but all with the same spectacular view, private patios, some w/a private pool (but there is a shared one on the property too). We had the AURA room which had a small kitchen, living room, bathroom and patio on the first floor and a bedroom and bathroom on the 2nd floor. The stairs to the upstairs bedroom are a bit steep and tight so be aware if you have accessibility issues. Ask for a one level room. A delicious breakfast overlooking the Aegean is served w/exceptional care every morning. After dark, when the town of Kamares lights up like a magical postcard, we listened to jazz on our well appointed patio and found it difficult to abandon that tranquility to go to sleep at night. We did not have transportation so George expertly arranged for taxi service when we visited other parts of the island, which was very reliable. George also arranged for the best tables for dinner. The towns in Sifnos are spread out; if you don't have transportation, you will have to rely on taxis (a bit pricey) or the bus system. I highly recommend Voya if you want a peaceful, elevated stay in Sifnos."

Ktima Vrisiana

10/10 Excellent

"We loved our stay! The location was lovely. We loved being surrounded by olives trees with beautiful ocean views by the pool. All staff were extremely kind and helpful. We had a car (highly recommended) so it was easy to travel around to different places on the island. I would definitely recommend staying here!"

ALK HOTEL™

10/10 Excellent

"We stayed at ALK Hotel for 2 nights, it's a great hotel, room was perfect with a little balcony. Staff were very welcoming, breakfast was included and had a good selection including fresh squeezed orange juice. Great view of the bay from the covered breakfast area and a great selection of drinks and snacks on the rooftop honesty bar. Enjoyed our stay and would definitely recommend."
