Four adults and two kids was our party and there were ample space for us. The downside was that the bldg was old and you feel the age of the bldg in the actual unit you are in. We had one snafu during our first night as one of they key didn't work. However the check-in team resolved it with in 15 minutes as they quickly came by to help us get back in.
All in all, our stay was ok. We had other family member staying close by in smaller units and felt their unit was much more modern and clean. Plus, we were coming from a nice resort in Douro Valley and that might have influenced our first impression.
