We sadly only had a two night stay here. Wished it could have been longer as the apartment was beautiful and in a perfect spot. Seven adults, plenty of room and lovely quiet bedrooms. The kitchen was equipped with everything we could have needed, and the living room had a large TV (which was especially good as the World Cup was on !!, although we spent little time in there.
Apartment is in an ideal spot for seeing the sights of Lisbon although wherever you stay, be prepared for lots of walking up and down the hills. Some great restaurants and cafe's nearby and some really useful little supermarkets to pick up essentials.
As Annabelle states, there was building work next door, but we didn't hear any noise.
