Sergio's apartment was great! It was much bigger than I expected for a studio. Everything was clean and the check-in process was easy to understand. Marie was a total sweetheart. She met us on the street for check-in and followed up to provide us with her recommendations for food and drinks in the area.
One note about accessibility--there is an elevator to the 4th floor, followed by a set of stairs leading up to the apartment on the 5th floor. This is good to keep in mind if you have big bags or mobility issues.
