We had an enjoyable stay at Eugenia and Luis's AirBnb, which is part of what looks like a small hotel in the middle of the city center and tourist swarm. The apartment was spotless and well ventilated. No air conditioning was needed in August. We loved the linens, which are very high quality. There is no traffic noise because the apartment is on the back side of the building but there was a fair amount of people and construction noise from the back street from approximately 7:00 to 23:00. We did not cook while we were there but the kitchen is well outfitted. Communications with Eugenia and Luis were outstanding and check-in was very easy. The front stairs, which are steep, can be avoided by going out the back entrance and down a short side street to the main street. There is another short flight of stairs to get to the apartment. it is a very easy walk from the Sao Bento train and metro stations. By the way, the bathroom is very narrow, so if you are wide, you may be happier in an apartment with a wider bathroom area. But don't hesitate to book with Eugenia and Luis. They have a well run operation.
