Sophia's place was the perfect stay for my first 2 weeks in Lisbon. It was super close to all attractions but still far enough away where you get a real feel for the city and people. Some of my favorite places in the city to eat and hang out are only a few blocks away.
Sophia was very responsive to all my requests/questions. The apartment had everything I needed, and if it didn't, Sophia arranged it quickly.
I will say that the apartment is in an old building, so there are a few things that people should be aware of before selecting the place. It is up to 2 flights of stairs, which was difficult with a big checked bag but doable. Also, you can often hear the neighbors. It didn't bother me, but if you are sensitive to sounds, it might not be the right place for you. The doors can also be a little finicky, but once you figure out the trick (usually to pull the door towards you if it opens out or away from you if it opens in), there are no issues. Would definitely book again.
