We had a nice stay here! The location is great - we loved this area of Alfama and found it was easily accessible to anywhere in the neighborhood (and close to a few miradouras!). It’s also about 20 minutes walk to Baixa and central Lisbon. Ubers won’t take you all the way to the house, but you can easily call one right up the road where you’d catch the tram.
The apartment itself is very spacious and has a lot of character. The stairs are definitely steep, especially with heavy luggage (I wouldn’t have been able to carry mine up - my boyfriend had to help). There is no AC so we were a bit warm at night, but they have 1 fan available which helped. The second bedroom does not have a window though, so I could see that getting quite hot in the summer. The wifi was also not the greatest. But overall, we had a pleasant stay!
