The house location is good, walk in 10 minutes to the good spot for sunset seeing, in 10 minutes to the supermarket and bus station. Nikos provides daily housekeeping.
He gave us drive service from and to the airport with potter help carrying our luggage.
Also Nikos has a guidebook in the room with a lot suggestion of touring activities, restaurants, bars recommend. This is helpful for us.
Anyway, this place is a good choice in Santorini Oia.
