Alfama is a very interesting place to stay in Lisbon.
Communication and check in went very smoothly - we were met by Paulo's wife. It is decorated in an eclectic way which makes the flat bright and fun. It was also clean. Coffee and tea were provided.
Paulo's place is as it states is small so it's really a place to have a shower, sleep and go - it's not a place to hang out - so much to see and do anyway. We stayed as 3 people and despite having a second bedroom (this has no door and directly leads in to the sitting-room so, no privacy whatsoever along with the opaque glass door to the bathroom which were very uncomfortable for our teenager ) it's really a place for a couple.
It's very close to restaurants and local amenities in Alfama and a short walk to the bus stop and metro/train station so it's easy to get around. Alfama in the morning and daytime is a quiet place generally. However, our first night meant listening to very close neighbours argue until around 4am which happened on our 3rd night also (it was the same Portuguese neighbours) and the noises from the children's playground (just along from the flat) which seems to be a local drinking spot in the very late evenings. I guess this may happen in many cities with people living on top of each other.
I would absolutely recommend going for breakfast at the Alfama bakery just a 5 min walk down the steps - The Pastel de Nata were the best I had in Portugal and the coffee and juice were great. There is a selection of sweet and savoury things to eat. We kept coming back for more and more.........

My big bug bear at the moment with Airbnb places even if they state that they don't provide them is things like shampoo and shower gel. It's meant to be a home from home and lugging around these things is such a pain. I think it should be standard as it was back in the good old days for Airbnb places.
Overall, it meets the needs to stay in Alfama.
