We had an amazing stay in Santorini and this apartment was a large part of that. It's extremely centrally located, about a 2 block walk from the bus station (1.60 euro cash pp from the airport) and surrounded by tons of food places we went to over and over again. We literally just walked outside and found spots to eat right away.
We felt like we could easily see all of Santorini on the ATV we rented, and having the ATV rental place next door to the apartment meant we didn't have to worry about parking or anything like it. I'm not quite convinced we got the best deal ever, but the convenience was appreciated nonetheless.
We'd stay here again and recommend it.
