Mela's is a great place to stay at Santorini, and Nancy is a perfect host :)
The aparthotel is centrally located in Fira (Thera) and the whole Santorini. It is close to everything in that so beautiful town, including the central bus station from which buses go to the other interesting places on the island and to the airport.
The apartment 4 that I stayed in is very convenient with a huge comfy bed, very good air condition, a very good WiFi and a place to sit with your laptop, a terrace, enough place to put your luggage and hang your clothes, and a nice bathroom. It has just been renowned, and everything was superclean.
Nancy waited for me patiently with the key although my plane was 45 mins late. She took great care to check together with me how the WiFi worked, as I needed to work at her place. She had no problem to bring me a few additional things I asked her for. Several times, she asked me if I need anything else. She does not answer her phone 24/7 but you can always call her some time during the day, and she always answers your text messages. She speaks perfect English, too. She is nice and straighforward person easy to communicate with.
I had a really wonderful stay at Mela's :)
