I just basically said WOW when saw the first time the flat and I´m probably going to type amazing a lot. The pictures don't do any justice to the actual place. It is clean and new, with amazing deco, The bathroom has a lot of space with a really nice shower and really long counter for the sink, the w.c. is in a separated room and also has another sink which is a nice touch. The kitchen has everything you need if you want to have some lunch or dinner, They left us a small breakfast for the three days that we where staying there consisting of coffee, bread, cookies, yogurt, fruits. which was perfect to start the day. Daniele has a little aqua book with all his recommendations of his favourites spots around the island and a small description of them, so its really nice if you have no idea what to expect of Santorini, plus a lot of other tips depending on what you are looking to spend you time.
The flat location was also amazing a walking distance to the center of OIA but also far enough from the busy tourist areas. You can also enjoy the pool and the terrace area of the flat which comes with furniture so you can relax there. For us it was perfect each morning we will go out and explore and then come back to relax in the pool for the evening one night we even stayed in to watch the sunset and have dinner instead of going back to town.
We had neighbours in the flat next to us the whole trip we got to meet them once, but we couldn't hear any noise and had total privacy even thou the flat is right next to us.
I totally recommend this place for your visit in Santorini.
