The apartment is very nice and spacious. The owners are super friendly people and will make the stay as smooth as possible. The room has a small balcony and the kitchen is accessible for free. The bathroom is in the room and quite small. There is no bidet.
Ordering breakfast is possible for 4€ per person. You can take for free umbrellas for the sea and local guide books.
The villa is located just in front of the bus stop which runs across the island once per hour (in summer).
Leni is probably the least known and most quiet area of the island comparing to the other two centres (Malfa and Santa Marina). However the Rinella beach is reachable within 5 min by bus or 25 min walk downhill.
A couple of restaurants and bars are at 5 min walking distance, including a supermarket (unfortunately closed during our stay) and a post office.
