We didnt get a chance to meet Ronnie, nevertheless, he was responsive and helpful - logistics went smoothly. He has a very nice cleaning lady who took care of checking us in (also from Denmark, speaks good English).
The place was nice and clean, has all the basics you would need (eg parasol to the beach). The apartment is on a quiet street.
The terrace is a nice addition, but make sure that you find the time to enjoy it - we didnt really have much to do that.
Metro station to the airport is a ca. 10 minute walk, city centre is right across the (dried-out) river.
Our only complain is that the central AC fan level is set quite high, you can only adjust the temperature and for us to sleep, the "wind" was blowing a bit too hard.
