We had an ok stay at Joel's apartment. The location is perfect, and the apartment is nice.
However, communication during the stay was not the best (before coming, and for the booking everything went perfectly), and even though we booked for 4 people, there were only 2 single beds and a single air mattress. Maybe in the other room he rents out there's a double bed, but this was occupied by another couple. Since we didn't see Joel again, due to completely different daily rhythms, it was difficult to talk about this while being there.
Anyway, being good friends this was not a big problem for us, but we figured it would be important to know for others.
