I put 3 originally but then thought they must be a bit higher I would have thought the top ones have good views and access to the sea is easy between the Hiona and the Amalia . I like that side of the harbour
We stayed in one of the Roulla studios three years ago with olympic. They are about 3 rows up and there is a lovely outlook from the terrace which is shared (a single storey row comprising 3 small studios). We had the one at the far end which was very poky and has a traditional sleeping platform - the other 2 seemed more roomy. Very basic but you really don't need much.
