Antonio was a great host. He amicably accommodated our delayed arrival time and met us at the apartment. The flat itself does indeed have a stunning view of the rest of the Alfama district and the Tagus River, and is overall an extremely lovely apartment. It's a great place to return to after long days exploring Lisbon, and is close to the famous 28 tram, for those not inclined to hiking the hilly streets. However, I highly suggest walking around, and Alfama is a perfect place to get lost on foot and stumble upon amazing tapas and wine, bookstores, etc. One could spend one's entire trip in Alfama, but this flat is a perfect place to call home base no matter where you end up in Lisbon. Highly recommended.
