We had a wonderful time at Zoia's apartment. The location is right in the heart of Alfama, very close to St. Jorge Castle and lots of amazing restaurants!
Zoia was super helpful and responsive. She provided clear instructions for check in (with pictures provided) and a long list of her favorite bars and restaurants. We checked in really late (1am) and she was still awake to answer our questions!
The space itself was very nice, clean, and spacious. You also have access to a terrace where you can enjoy breakfast and watch the tram drive by.
I would absolutely stay with Zoia again the next time I'm in Lisbon!
