I absolutely loved staying in Simos' apartment in Merichas in Kythnos. The place is so cozy, very clean and comfortable and with a perfect location. It took max 10 minutes to walk from the ferry - and it was very easy to find with the comprehensive instructions from Simos. Just beware of the long staircase up to the apartment, which can be a bit tricky with a huge suitcase, but Simos had prepared me for this :-) The apartment is close to everything in Merichas, it has a very nice and big balcony with morning sun and beautiful views of the port and a fantastic swinging chair, which was just an additional extra touch for me. In addition, the kitchen is fully equipped, and the rain shower was also just a plus in my book :-) I stayed here alone as a solo-traveler, but would say that the place is probably most convenient for solos or couples, it might be a bit tight with space for 3-4 people... Throughout the booking and stay, it was very easy to communicate with Simos who answered promptly and kindly on all my questions and messages - and he even made sure that there was plenty of water in the fridge for my arrival. Can only recommend this place, and will definitely stay here, if I go back to Kythnos (which btw is very much worth a visit).
