Amazing place to stay in the heart of Lisbon. You’re very close to everything you could want to do - great shops, sights, and food. You are also a 10 min walk to the Rossio train station, if you wanted to take a day trip to Sintra.
The unit itself was neat and tidy, with a great view from a first floor balcony. The double paned door ensures noise is not a factor, despite being next to a busy street.
I also really appreciated the attentiveness of the Residentas team. We asked for a few accommodations and they were more than willing to help. They will be one of your best friends during your trip. I can’t recommend them enough.
