Great stay in the medieval quarters of Lisbon. The stay is about a 2-minute walk from the flea market on Tuesdays and Saturdays which I would consider a must-see in Lisboa. I would also recommend a free walking tour of Alfama to learn about the history of the neighborhood and get acquainted with the windy and hilly streets.
Check-in was simple and the employee who greeted us was very accommodating, do note that there is a 25 euro cash payment for checking in after 21:00. This is on the listing, so I'm not docking any rating at all, but wanted to make sure others consider booking know this.
The fridge is a little wine fridge, so if you plan on cooking or eating leftovers plan accordingly.
Ultimately, I would recommend this stay!!
