The best part about staying in the apartment was Diogo's communication. Even though we did not meet him, he was easy to reach and was always happy to respond to any questions. He also offered local suggestions for where to shop for souvenirs in Lisbon.
His place was right in the center of Lisbon and was near a train station, a convenience store, and lots of shops and restaurants. I guess depending on the type of traveller, the dive bars on one end of the street could be a pro or a con. Weekends can get a little noisy as the apartment is on ground level. The place itself is on a historical street where the famous yellow trams run therefore also gets a lot of foot traffic from tourists.
Overall, the place is okay for a short stay but needs a bit of updating especially the bathroom. Cleanliness could also be improved.
