Carmen was very patient, especially when I got lost trying to find the place. Taxi driver will get you to the plaza nearby, but make sure you can navigate from there to the little pedestrian-only street. I should have printed out a map (phone was dead after a long flight and train ride).
Location was great. Apartment was very quiet at night, except the upstairs room neighbors were a bit noisy a couple of times. The ceiling of the upstairs room is a bit low - if you are over 6 feet tall you may not like it as well. Bottom bedroom was great, so was everything else. The apartment was well equipped with everything we needed.
