We stayed in the apartment - 3 couples, so we were 6 people. The place was really clean and comfortable - we did not see one bug! Also the common area is quite large - we could hang out and chill in the apartment as a group.
The area is also great - there is a nice coffee house with great coffee across the corner; supermarket and bakery in walking distance. The super plus is being so close to the beach! Going for a morning swim is something we did every day. The down-side is that the walk to the metro is quite long - 20 minutes. But if you are a good walker, it should be fine.
There is only one thing we would recommend: The mattresses of two of the three bedrooms are really old and lain-off. These should be renewed.
We really enjoyed our stay and can highly recommend it!
