The flat is near the airport, the beach, a few restaurants, a little market and a bus stop to go to other cities (about 20 minutes away from Fira by bus).
There is a private entrance, a TV, a kitchen with everything for cooking, towels, shower gel... We only missed shampoo.
I recommand to buy bottles of mineral water.
The area is a bit isolated and not crowded.
The host was very kind to pick us up at the airport on the evening and very helpful.
