This was the best Airbnb experience we have ever had. The bedrooms and the living room were all very comfortable, which is important to us. We were particularly impressed by all the large windows with electric blinds that block out the light so effectively while we slept. The pictures are very accurate - the view is wonderful, particularly late in the afternoon with the sun shining on the hill.
Check in was easy. Cristina was waiting for us when we arrived and helped us get our rental car into the parking garage. She gave us some suggestions for local restaurants, and the one we tried (Martinho da Arcada) was wonderful.
I don't know Lisbon all that well, but it seems apartment's location is just about perfect. The famous Tram 28 ride starts across the square - you can sit in the living room and watch people climb aboard. Tram 15E to Belém starts a 5 minute walk from the apartment, and the Rossio train station (where you can catch the train to Sintra) is probably a 7 minute walk. It was also easy to walk through Baixa and Alfama. There was a nice sidewalk a half a block from the apartment building where we had our cappuccinos every morning.
It was a wonderful stay. We can't recommend it enough.
