Me and my boyfriend stayed here for 10days. We both very much liked the apartment, it looks quite stylish and it offers enough space for the both of us. It was also very nice of having the ability to cook, the kitchen was spacious and we'll equiped. The airco is a necessity during the summer and it cools quite good. Downstairs tends to get quite warm, but the van offers a solution. So about the humidity, I didn't felt it, only that the (former) humidity showed it effects on the walls I guess. Felix also responded quick to messages which gives you a comfort feeling when you're the one who's visiting. I would choose Felix's apartment again :)
