Lovely place, very clean, had everything we needed. Would stay again! So things to note: We stayed on the 3rd floor which is like the 4th floor as there are shops at the bottom so the first floor apartments don’t start till the second. The stairs are steep and narrow but we had no issue climbing them with a baby and my grandfather was also able to climb them. We had a stroller we left at the bottom of the stairs without issue. The house overlooks the pedestrian street below and it will be noisy. We didn’t mind it at all (I used earplugs). It’s easy to get a taxi to the airport at the closest street for about 10 euros. It’s a close walk to Rossio station (5 mins) and we went to sintra for the day. Also close walk to the fort (20 mins). There’s nice restaurants around the house.
