I'm happy with my decision to stay here and enjoyed the great view! I am grateful for being able to stay here and Isabelle was readily available for anything I needed.
This new unit is on the top floor in a very quiet neighborhood. The neighborhood and building are very safe. The AC works great and there were 2 units (it was hot when I stayed). It has automatic slide blackout windows great for sleeping and noise. Nice appliances, hot water, and it was fully stocked with everything you need. The washing machine was super useful.
As for public transportation, you need to be prepared to walk up and down the hill(s) . This is true in Lisbon, but there are definitely better areas than this location for having access to the major lines and metro that would be relevant for touring. There are two bus lines that are in the near block or so, but they do not connect in convenient ways across Lisbon. I found myself having to take multiple connections to get to certain sights. For example, if you want to have easier access to Principe Real and Barrio Alto, then you might want to consider staying in that area. Additionally, you can walk to the metro, but be prepared for a long walk up the hill after your day of touring. I found myself using Ubers and Taxis after long days traversing Lisbon.
If you want to bring a car, then there is parking in the basement. In my opinion, if you're comfortable with having a car within the city limits/streets, then use one. A lot of people in this neighborhood seem to have and use their cars.
