We really had a great time in Koutalas. Don't know how it works in high season but you definitely have to rent a car or get a cab to reach the house as it's quite far from everything if you come after september 15th. Also, there is no supermarket or any restaurant open, so you have to make provisions at the supermarket when you arrive (we did not know that and there was nothing opened around...normally there is a taverna that has just closed a few days ago as the taxi said so nothing to eat on the morning as we planned to have breakfast there...but yeah, it was part of the experience). Pb of communication btw Vaggelis and his grandfather resulted that we were expected the day after but we just had to wait a while for him to clean the house, nothing bad. Vaggelis grandfather seems to be a really nice guy, too bad that we could not really communicate as he speaks only greek. Ok, now the house. It's really small but we found it fine for a couple and the terrace was just perfect and is really the best of the experience. Having a beer, watching the stars in the hamac is really something! You really have privacy and feel like you're far from everything which was what exactly we expected. The shower outside is nice too (but sometimes it was too cold back from the beach at the end of the day, so you also have a small shower inside don't worry). Only thing is that you should not be afraid of wasps because they were our guests all the time (but if you don't fight them it should be ok...) One last thing, don't miss the Agios Sostis beach in Serifos (our favorite, really amazing) and don't expect a sandy beach close to the house as it's rocks but still nice to take a bath 5 minutes walking from the house!!
