My boyfriend and I booked two weeks in Santorini in June.
This hotel is in a great location,with its entrance just off the beach, although hard to find the first time (and also after one too many cocktails in the evening!) , about 15 mins drive from the airport.
We booked a double room with breakfast, the room was quite small but had a terrace and a small area for dining, the breakfast was the same everyday so in heinsight it might have been better to not pay upfront and get our breakfast from the nearby bakery instead. The room was pretty basic, but clean, and the sheets and towels were changed everyday.
This hotel probably suits young people on a budget, it wasnt quite the luxury we were after, but having said that, I cant really fault it either.
The hotel has a small pool (which we didn't need to use as the sea is so close by) and the staff were really friendly and helpful.
Perissa itself has lots of bars and restaurants (but you cant hear them from the hotel) and a good beach, and as the island is small its a great base for exploring. I'd definitely recommend hiring a car and driving about to see the island.
Favourite restaurant was Atlantic Island, just 5 minutes walk away.
Best find of the holiday: the sleepy looking village of Pyrgos, its worth the climb to the top to find the cute tourist shops and the amazing views of the churches.

i stayed here for 5 nights
amazing staff, very fun and friendly.
great location, you walk right onto the beach :)
very clean and nice spacious rooms

We stayed at Anny's for seven nights. The location is perfect, literally a minute from the beach and next to one of Greece's more exciting reataurants (Ntomatini). When traveling with three kids we often have to split into two rooms, but the studios here are just perfect where the kids even got their own loft. Also affordable prices. Silent and efficient AC, an ok kitchen, clean WC, nice staff, balcony with sea view, efficient booking of trips in the lobby. A small but very nice pool and and a nice Australian girl in the pool bar. We had a great week!

great location, just off the beach. the staff were really helpful. not enough kitchen utensils and wifi did not work in the room, so you have to sit on the balcony with a gorgeous view of the pool and bar. bathroom was the smallest i have seen, but our room was cleaned every day.
we had free pick ups and drop offs at the port, which was so convenient. staff also organised us to hire a ATV for the day, which is the best way to see this amazing island. would recommend to anyone and would certainly stay there again
