We were 4 adults. Great location, very clean apartment and sheets, with comfortable mattresses. The sofa-bed is not so comfortable though, but ok. I think it's important that guests know the floor is not leveled, specially in the main double room, which caused my parents to not sleep comfortably, as their feet were significantly higher than their head (or the other way around if you turn your body). Bathroom is small and the area is noisy at night, as other guests have said. If you plan on sleeping on the single bedroom bring earplugs, they are a must. We unfortunately had very noisy neighbours upstairs during our stay too. Comunication with Nelson was easy and helpful.
