I stayed one week at Provis Rentals and here my personal experience and meaning :
Positive :
- correspondence before my arrival was fast and friendly
- very clean !!
- big enough for 2-3 people with many storage place
- enough and different kitchen equipment
- confortable bed for a great sleep
- decoration is absolutely lovely !! Lots of nice and local objects that makes the apartment really cute and charming
- they changed the sheets and towels in the middle of the week which was (even if not really ecologic) a nice unexpected surprise
- central ! I read people complaining about noise but it wasn't that bad at all. Of course you hear when people outside speak loud or sometimes the workers from the restaurant which is very close but that's normal : you're staying almost at the center and that's absolutely great !!!
Negative :
- access to the 'balcony' was blocked
- the tv only worked one day, every time there were other reasons why it didn't work.
- the safe never worked and also there were always excuses
- the correspondence was a little 'strange' later on ...
But finally I really recommend this place. The negative points are almost forgotten and only the good souvenirs stay back from my stay in a typical Mykonos 'house' :-)
