We have several extra beds ( used when you are more than 6 in your group) for children and adults. Two of them are normal beds with thick mattresses and are normally comfortable; 2 others are foldable with thin mattresses but easy to use , they are good for light people and kids but can be not very comfortable for rather heavy adults. So please just talk to us if you have any comfort problems.
The harbor of Kotor is rather far away and it is only for yachts and cruisers, the yachts do not pollute really and the cruisers follow a very strict clean policy ( they should not left a gram of dirt in the bay) and are very strictly controlled. There are several underground rivers coming from the mount Lovechen ( Just above Kotor) washing the bay , so even if it is used as save harbor for already 3000 years it is still normally clean. After heavy rains , however , when the rivers flow is very strong the water in the bay becomes a bit melted with sand , but not dirty. 200m from home there is the Institute of the See controlling the quality of water all over Montenegro and rising colored flags on the beaches to prevent people in case of bad water.
