The hosts: Rui communicated well. He was easy to get in touch with, made sure there was someone waiting to give us the keys, and responded to requests while we were there.
The flat: Cozy, as described in the photos. A kitchen, bathroom, and double bed. The windows look over the Alfama neighborhood to the water. The flat was tidy and had everything we needed. The location was perfect. Alfama has a lot of character. Around the corner is a cluster of orange trees, which were a pleasure to stand under. There are restaurants and cafes nearby -we had a wonderful meal at Santo Antonio, which has a patio, and excellent local food. It's easy to hop onto the No. 28 tram, which is a historic tram that rumbles in a circle around the city. There's a viewpoint where you can see much of the city, which is a climb away. Historic sites like the Sao Jorge castle are also a short walk away.
The only access was via stairs, so if you have difficulty climbing, or are very tall (this is an older building) perhaps there might be some challenges.
