We arrived on Christmas day, which is complicated as the owners were busy with their families. So we found our way to another place that they own and Susana's sister-in-law was very courteous and took us up to the Alfama apartment. It looks just like the photos. Modern and clean and nice.
But, we had bad luck. The stove did not work and the cable did not work. When we emailed Susana, her husband, Joao, came by immediately. He confirmed that both items did not work and he tried to fix them to no avail. Alas, we were able to use the stove next door and the cable repair guys arrived the next morning. Then things went smoothly, until the day before we left. Then the electricity went out in our apartment, no where else in the building. And it was New Year's eve at 8pm, so it just seemed too complicated to get help. So we spent the night in the dark and left for the airport in the morning in the dark. (No candles available or flashlight.)
We had a nice stay at the apartment but for a 6 day stay there were a number of glitches. We still think that the place was very clean and nice, that the location is fantastic, that we got lost all the time in Alfama which was great fun and we expect that these are not typical events with the apartment. Susana and Joao, the owners, were pretty much absent and I don't know if that is typical for an AirBNB stay - but we did fine with the apartment ourselves. I would stay there again. (Recommendation to others would be that a Taxi ride to Alfama from the airport should be about 8-10 euro. Our ride there we were grossly overcharged. We were smarter when we took it back on our way out of Lisbon.)
