Marcia & JC's place was exactly what we were looking for - something at the heart of Centro Historico with easy access to tourist sites and public transport. The place was very secure, staff were very helpful, and Marcia & JC were available for a few extra requests we had (more trash bags for example). We did not find the street noise that loud, especially if you put on a fan or some white noise. However, the building has quite an echo so people walking, dogs, etc, moving upstairs is all pretty noisy. Otherwise we had a fantastic stay.
