My name is Konstantina (Greek) and I want to share my experience regarding the stay i had in Cavo bianco studios in Donousa this summer (2019).

The room was an old fashonied small one with no air condition. The shower was extremely small with no curtain for the unnecessary waters!. The mattress of the bed was very old and not at all comfortable (we feel the springs in our body!). And,the worst of all, was that we didn't have hot water 3 of the 5 days of our stay, with no excuse.
Although the above, the owners were impolite and not at all professional, something that we did confirm from other local people.
Honestly, do not be fooled by their nice web site. Our room was not photographed in the site.Honestly we really wonder if they had ever renovated their rooms.
