I enjoyed my stay at Carmen and Sergio's apartment. The location is superb with close proximity to all the major attractions and an easy bus ride from Santa Justa station. Sergio was a responsive and hospitable host. I would recommend this apartment to everyone, with one caveat. The noise from the residents above carries into the apartment and it can be very loud in the evening. This did not bother me but it is something to be mindful of if you are an early/light sleeper.
