Bruno's place is superbly located in a cozy part of town, no more than 10 minutes walk to Cais do Sodré and the TimeOut food market. Lisbon is a city full of steep cobbled streets, and Bruno's place is no exception, so prepare for a calf workout!
While I did not get to meet with Bruno in person, he was very attentive and helpful. His friend Ana and her husband - who run the cafe on the same street - were there to give me a warm welcome at check-in which they facilitated early, and I felt comfortable knowing they were nearby if needed.
As others have stated, the apartment does not receive much natural light, which was not an issue for me but for others maybe. The apartment was cool, but not cold, and there is a small electric heater if you need. Kitchen is fully equipped, including a washer / dryer which is rare! Shower was warm and powerful. Bedroom was cozy and very comfortable, I slept well during my stay. Others have noted than the street noise can be slightly loud, however I found this did not go on late and did not disturb me while trying to sleep. WiFi was fast and reliable.
Overall I had a very pleasant stay in Lisbon, with big thanks to Bruno.
