My sister and I stayed at Maria's apartment for 3 nights and it was an incredible experience. Maria was very responsive and communication was a breeze. We never met Maria, but her staff was equally as helpful and wonderful. We arrived earlier than the check-in time, and they were nice enough to store our luggage so that we could roam Oia. Oia is a beautiful place to stay and the views the apartment has are amazing. Since Oia is known for having the best views of the sunset, it did get pretty crowded around that time, but you can't hear the crowds from the apartment. The bus stop is a less than 10 minute walk and restaurants and stores within 5 minutes or less. Something to consider is that there are quite a lot of stairs to get to the apartment (as with a lot of places in Oia); we did a lot of research beforehand so we packed lightly in smaller suitcases so that it would be easier to navigate around. We had a lovely time in Santorini and a major part of it was due to how much we enjoyed staying in this apartment.
