Overall the stay was decent, the location was ideal for the wedding we were attending nearby. Access to public transit is ideal if you want to head into Lisbon, though it's like 45 minutes. There are a few local shops nearby worth checking out.
Unfortunately the unit can get quite stuffy if you leave the windows closed, but opening the windows, especially the front one invites the fast moving and loud traffic sounds to overcome the unit and it gets quite annoying very quickly... especially with racing vehicles and motor bikes charging by.
During our stay there was a mold or mildew smell prevalent in the kitchen sink area. There were also lots of fruit flies buzzing around as a result. The bedroom closet window appeared to be stuck open slightly, this led to cigarette smoke and/or marijuana smoke permeating into the closet where our clothes were. If we left the closet door open it flooded into the bedroom. The floors were also not properly cleaned, walking barefoot on them or in socks it was very apparent that dirt was being left behind on them as we walked around. The garbage bag also did not fit the garbage can in the kitchen. There were only two bathroom towels available, so if we decided to go to the beach or visit a friend in a nearby hotel we had to bring those same towels with us. It also would have been nice to have a roll of paper towels in the unit.
Overall the unit worked for what we needed, but we would probably select a hotel or a different location if we ever went back.
