We spent a few days here and loved every minute! The apartment is in a lovely location, right next to the castle, which was our favorite thing to see in Lisbon. Expect steep hills, but the walking is well worth the incredible views. The apartment is clean and comfortable, and stocked with the basic things you need like shampoo and coffee, etc. We didn't get to meet Paulo, unfortunately, but his friend, Amelia, met us and was very sweet and helpful. They were flexible with our check in and provided resources for enjoying our stay. I highly recommend booking this apartment. You will not regret it.
