We enjoyed our stay at Olga and Paolo's apartment. The apartment is just the right size for up 4 people--two double beds, each on a separate floor, and two bathrooms, each on a separate floor. The kitchen is well equipped for preparing easy meals.
The location is very convenient and close to Rua de Santa Catarina--a main pedestrian friendly shopping street. There is a grocery store just up the street about a 3 minute walk.
The full length windows on each floor let in a nice amount of light during the day and open onto balconies.
This didn't affect our stay, but be cautioned that the apartment is on the 3rd floor (European) or 4th floor (American) and there is no elevator in the building so you will need to carry your luggage up several flights. Was not a problem for us, but could be an issue if you have mobility issues. Also note the second bedroom and bathroom are reached by a spiral staircase. Again, not a problem for us, but something to consider depending on your agility.
The apartment was comfortable and nicely decorated and spotlessly clean when we arrived. We had a chance to meet Olga and Paolo for a few minutes when we first arrived and they were very friendly and welcoming. They have a folder on the table with information about local shopping, restaurants, etc. Wifi worked fine the entire time we were there.
We would definitely recommend the apartment and our hosts!
