We had a nice stay at Ana and Márcia´s place. The apartment is very nicely located, not directly in the buzz of the city, but in walkable distance from all the sites. We actually enjoyed the slightly more quiet neighborhood. Communication and check-in was all very straight forward and easy. The apartment is well equipped besides some soap missing in the bathroom. We traveled to Porto in November and some chilly evenings which you could also feel on the apartment. But if you are looking for a rather neutral and well located place to stay Ana and Márcia´s apartment is definitely to recommend.
