It is hard to say what we loved best about this place because we loved it all!
The house is simple but very tastefully decorated and equipped with everything one would wish for a great holiday (including two sea kayaks and many books and toys). The location is absolutely perfect: right on a beautiful beach that has few visitors despite being just fifteen minutes walk away from the island's many restaurants. Alina is a great host: it was very easy to communicate with her and her sense of hospitality was obvious in all the little nice touches waiting for us when we arrived.
The only small defect of the house is maybe its proximity with the next houses, so one does not have a lot of privacy but we were lucky with our neighbors, so it was not really a problem. Also note that the beach in front of the house is a favorite among nudists, so it is rather common to see naked people sunbathing or swimming.
The Island of Serifos, where the house is located , is also really nice, we loved visiting the Xora and the shops and restaurants in Livadi. We would love to go back one day.
In summary I would 100% recommend Alina's house to anyone!
