We had a week stay in the Campolide apartment which is on the 3rd floor of the beautifully renovated building. The apartment was clean and spare with just the things required for a good time. The beds were comfortable, the kitchen stocked with all tools/pots pans required to cook light meals. The bathrooms were a good size, with the requisite number of towels. The living, eating and cooking area is a good size and very comfortable for our group of four. We had a nice balcony which overlooked the city.
Nathalie was an attentive host who met us very early in the morning to let us into the apartment (we had reserved the apartment beginning the night before we arrived so we could enter immediately upon our arrival). She also recommended some area restaurants that we very much enjoyed (Treestory, just across the street). We also liked PSI Vegetarian restaurant down the street. She answered our queries quickly.
There are a couple of things to be aware of: One must climb a couple of small flights of stairs to reach the elevator and then it stops at half flights requiring more steps up and down to reach the apartment. We did not visit the garden because one had to use a staircase which is very steep (we had one member of our group with a broken arm and another recovering from a knee injury). Neither of these detracted from our visit because the benefits of the apartment outweighed these things.
