We had a wonderful stay at Megalochori at Eirini's apartment.
The town is ideally located to visit Santorini, it's an authentic village with everything you need (bakery, mini markets, good restaurants...), with charming streets to wander in.
The apartment is very nice, clean and we'll equipped. It was perfect for our family of 5. The terrace is great and the park place is a few meters away so very convenient. We had the chance to meet the family who leaves upstairs and they were really nice.
Last but not least, Eirini is an incredible host: she gave us a lot of good advice on where to go, where to eat and what to do. She is super quick to answer and very kind and caring (for example, she had put some food in the fridge for our first breakfast since our plane was arriving very late at night).
A beautiful place to stay for a holiday in Santorini !
