This unit was wonderful! You share the pool with the rest of the units but overcrowding was never an issue. I fact, most of the time we had the pool to ourselves. Everything was very clean and well organized. You get a great view of the mountains. Roussetos was great! He was very accommodating and was willing to work around whatever scheduling problems arose. We were picked up at the airport and also dropped off at the port to catch our ferry to Athens. We were also able to sign up for tours and rent cars from him really seamlessly and they were all very affordable. It was an unexpected convenience to be able to arrange our whole trip in Santorini through one person. I highly recommend the tours. Driving in Santorini was also a cool experience.
The one thing to note is that you might not necessarily get the unit that's shown in the pictures. We arrived and got checked in to a different unit in the same apartment complex so everything was still fine and the unit we got was great but it's just something to note.
