We had a very comfortable stay in this centrally-located apartment, half-way up one of Lisbon's hills. The location is great for cafes, sightseeing and convenient for popping back to for a rest before heading out for more sightseeing or dining. The space is a good size and the furnishings attractive. Lisbon is a busy, vibrant city and people go out late in the evening and stay out until the early morning. As such there is street noise in much of the centre of the city. Rui's apartment is quite good as far as nighttime noise is concerned, but it was still easier to sleep with the balcony doors closed and the AC on, than with the windows open (even though the evening breeze meant the AC was not strictly needed). The apartment is on the 4th floor of an old building with no lift. The staircase is a little narrow too, so I highly recommend duffel bag, backpack or small suitcase. Getting a large and heavy suitcase up and down the stairs would be a challenge.
