+: excellent location, apartement has everything you need, communication with hosts is easy and fast, altough lisbon is noisy city the apartement is quiet(no noise from the street sometimes a bit from the neighbours)
-: a bit small for the price, no window in bedroom so we both wanted more oxygen, if you stay for a longer time u want to change your sheets(and towels) but thats not possible(you can wash them but no drying rack so you will never have them dry for the next night)
Overall i would say, good choice for a few days. For a longer period maybe not.
