I just spent 5 nights at Alexandros Resort in Livadakia, Serifos, and I can't say enough about how beautiful it was. The views from the room were breathtaking, and the staff was incredibly friendly. The breakfast options were fantastic, too! On the other hand, I also stayed at a hotel in Sifnos but felt it didn't quite measure up in comparison. Has anyone else been to these islands? What were your hotel experiences like, especially in relation to views and service?
