First, thank you to Lucy and Mat! We loved your place.
It is a one bedroom place on the fourth floor, and the building has an elevator. Although there is one flight of stairs that you need to use to access this rooftop apartment. Great view and location (near restaurants, metro). Loved sitting outside at night with the bottle of wine from the refrigerator :)
A friend (who lived in the building) checked us in. She was extremely helpful throughout the stay, also an easy checkout. Our flight leaving Lisbon was late afternoon, and they let us keep our bags there until our departure - we kept the keys and left them on the counter when we left.
The only downside was our stay was 2 days in the summer, and it was unseasonably hot. No air conditioning which is ok (described in profile) but maybe recommend a fan for those few weeks in the summer when it is hot. It was slightly uncomfortable to sleep. Everything was in working order (bathroom, lights, fridge, kitchen), and they also had a terrific welcome binder with recommendations for food, activities, and transportation.
We definitely recommend this place!
