This is a beautiful, tiled apartment located right in the center of Lisbon. There is some background street noise during the day, and at night the noise can increase a bit in the living room until the pretty late hours, when it dies down. But we found the street noise not to be a problem. If you close the windows, the noise is muffled somewhat. The bedrooms are in the back (one has no window, and the other has windows opening onto narrow spaces between buildings rather than the street) and are very quiet, comfortable, and well set up. Great for sleeping.
The kitchen has everything you need, including a washing machine (no dryer, but there is drying rack that works quite well), coffee maker, electric tea kettle, toaster, etc. The location cannot be beat -- very central in Lisbon, and you can walk to most of the places you might want to visit, and hundreds of places to eat. As others have mentioned, there are three flights of stairs up to the apartment, with no elevator. The stairs are modern and even, so a little better than some I have seen, but if you don't want stairs, this is not the place for you. We had no problems, but if there had been any problems, Joana seemed very easy to communicate with. We were met for check-in, and check-out was very simple. Very highly recommended, and we'd readily come back when we have the chance to return to Lisbon.
