The flat was great! We were 4 and had a lot of space.
Eirini is a great host. She organized a taxi transfer for us to bring us to the appartment and we could bring our luggage even before check-in time!
She gave us a lot of tips what to visit and where to eat.
The flat was very clean and the fridge was filled with fresh local food (cheese, vegetables, butter) and drinks (milk, water). The kitchen was fully equipped even with everything you need to cook (oil, vinegar, spices,...) and have breakfast (jam, cereals,...).
The location of the flat is great, just a few minutes from the port and the okd city centre, a supermarket is next door.
I highly recommend this flat for a stay in Naxos!
