The stay in Pedro's apartment in the middle of Alfama was very pleasant. The apartment was very clean and equipped with all basic needs. The bed was fantastic and the view is also wonderful.
If I really want to be picky I would mention two small things worth noting.
1) Alfama's streets are paved and you can only get to the apartment by foot. There are many other Airbnb in the street which leads to the fact that every night tourists arrive until about 1 o'clock with their suitcases and you can hear that very well even from the 3rd floor. The apartment is at the 3rd floor you reach passing through a very steep stairs with no elevator. Since Alfama is also a neighborhood with many restaurants you have to know that especially on weekends it can still be loud in the streets till late.
2) Pedro's apartment is very nice and divided into two floors. You get to the upper floor with the bedroom via a small staircase. From there you also get to the roof terrace. However, the sloping roof is so deep (1m) that it is very easy to hit your head if you are not careful. I would somehow cover the edges with foam because it can be very dangerous.
