Room seems big in pictures, but the pitched ceiling takes a lot of the space on that side of the bedroom (a bit of a hazard to wake up in the middle of the night and forget that rafters are there). My biggest issue was in the bathroom: lighting is very poor making it hard for doing make up and getting ready, next to no space on the vanity to place toiletries, no ledge of shelving in shower so you have to place everything on the floor (shampoo, shower gel, etc)
Location is nice, close distance to 2 view points (miradouros), it is located on the hills of Lisbon but close to sites of interest and the hike is not bad at all. Bed was comfortable, 4th floor has a nice view, elevator works well and everything seemed really clean.
