The pre-visit check-in procedure is rather arduous and means to contact the owners not easy.
I requested the option of 2 single beds but that didn't happen.
That being said when we did receive the check in details it was very easy from there on. The apartment is nice and super well situated. We were disappointed that there is absolutely no basic necessities in terms of beverages, including water, on arrival and in some ways the apartment could benefit from some maintenance and thought, e.g. bathroom door doesn't lock, no bedside light. There are so many interesting places to visit within easy walking distance so we did, overall, really enjoy our stay and would definitely stay here again as the benefits far outweigh the negatives.
