Pros:
This space is wonderful, with ample room and a well stocked kitchen. Everything was clean, well organized and they even gave us a free bottle of wine upon arrival. Host was gregarious upon arrival and was in constant communication before we arrived. He offered suggestions on what to see and how to get around from the apartment since there was no direct public transport in the area.
There is a nice cocktail bar directly below the apartment and a small cafe and restaurant at the end of the street.
Cons:
Took my 58yr old mother here, and the steps getting up to the apartment were a challenge for her by the end of a long day exploring the hills of Lisbon. They were steep and with narrow treads. So if you are traveling with someone a bit older, this is a consideration.
I wish there was AC, because the noise from the fore-mentioned bar and restaurant often lasted until 2-230am, but the windows needed to be open for ventilation. Ear plugs solved that problem immediately. This did not ruin the trip, but just something to be aware of.
