Highly recommended!! This place and neighborhood are so charming. It's the perfect location within walking distance from the major attractions!! If you're a foodie, Casa Guedes (known for the sandes de pernil, pork sandwich) and Gazela (home of the original Cachorrinho, an Anthony Bourdain local recommendation) ++ many restaurants, bars, and bakeries, the grocery store, and pharmacy, are each 5-8 minutes-walk tops.
I can speak to two challenges. The first, which adds to its charm, is that it is a pedestrian-only neighborhood. You'll have to shlep your luggage through a cobblestone neighborhood to get to this charming place. You only have to do this on arrival and departure so not a big deal. Well worth the minor hassle. The second challenge is the Wi-Fi. The connection was not strong enough to support video calls well. I worked only briefly (visited the week of American Thanksgiving) so this was not a huge issue, but be advised.
