The location of the apartment is ideal, it is 15min to the cathedral and the São Bento station. There are many opportunities for markets, bars, restaurants nearby. Also, the bus stop is just 2min away. The apartment itself is really pretty and welcoming.
Communication with Ana and Daniel is okay, they reply fast. We received the details to the check-in a couple hours prior to our stay.
Important to mention is that the apartment is located on a very busy street and the windows are located on the street side, so if they are open it is really loud. Also, the walls are very thin, so if people go by the apartment in the hallway, one hears them tramping and talking. Additionally, you also hear if people are walking in the apartment above.
