Our stay with Kostis was great. We stayed for 3 nights. He was very responsive prior to our arrival, and arranged a transfer from the port and another transfer to the airport. He met us personally when we arrived and was quick to respond to any questions during the stay. The house was really charming. Small, but with a big patio. The whitewash and blue doors are beautiful - other tourists kept stopping and taking pictures of it from the street. The kitchen is fairly well equipped, and there were juices and bottled water waiting for us when we arrived. Privacy is a little tricky if you are more than 2 people, since you enter into one of the bedrooms, and have to walk through it to get to the other. Having the hotel next door was great - we used their newly renovated pool and they also were very helpful with suggestions of things to do. The beach is just across the walkway, less than a minute away. It was not warm enough for swimming when we were there, but we did dip our feet and lay on the beach a little. The black sand is very striking, although parts of the beach are not as soft, tough on the feet. It was a bit loud at night sometimes, as we are right on the walkway and near a bunch of resorts, but it didn't bother us much. During high season this might be an issue if you are a light sleeper. Getting to Fira is fairly easy and cheap using the local bus. Overall, we really loved this place. It felt much more of an authenticate experience than staying in a fancy hotel (in Fira or Oia, for example) and the price was reasonable. Definitely recommended!
