Every time the front door opens, it makes a sound like an alarm. So when you are staying in the apartments on the first floor (like us) it wakes you up everytime the door opens. Especially when other people come back home late. The apartment is small but had everything, just didnt like the smell of the bedsheets and towels but thats personal preferrence. The swimmingpool area was nice, unfortunately it was too cold to use it when we stayed in Lisbon and the commute to the airport is very short.
