We stayed at Meli Meli for one night on our way to Crete. We were surprised to find Meli Meli is run much like a wee hotel. The concierge service is actually provided on site. Panos was very helpful with any questions we had.
We were able to get a full continental breakfast for 10 euro each. You have to walk (or get a taxi or other transportation) if you want breakfast otherwise. We opted for the in house breakfast as we were only aware of two places on the caldera path between villages which served breakfast and had not bought anything from a supermarket. We think that the price at Meli Meli for breakfast was most likely comparable to a bought breakfast elsewhere without the hassle.
We stayed in the suite above reception. The suite looks just like the pictures, the bathroom is a little small for what we are used to but was practical and we managed perfectly fine. It was actually bigger than some of the bathrooms in hotels we stayed in earlier in our trip around the mainland. Bonus points for the pool!!! We spent a few much need hours of rest by the pool and it was perfect.
Meli Meli is situated on the main road between Oia and Thira so there is traffic all the time and being on the top of a hill it is also very windy at times. We are used to these things where we live but for those who are not I would recommend being prepared with ear plugs. Don't let is put you off staying at Meli Meli as it is a lovely setting otherwise and we had a great time here if only for the one night.
Overall we had a really enjoyable stay at Meli Meli and would happily return or recommend it for others. Meli Meli is proof that you don't have to stay in Thira or Oia on caldera to have an enjoyable Santorini experience.
