The apartment is really nice with modern upgrades. It is at a great location just steps from Plaza Mayor and Mercado de San Miguel, and right on one of the best streets for dining (including the oldest restaurant in the world) and enjoying Spanish tapas. It is within relative walking distance from metro stations. At night it was quiet, and we were able to rest. We did encounter an issue with the apartment having an unpleasant smell. We determined it was coming from the bathroom (sewer smell). The bathroom was very clean so it was probably an issue with the siphons/drains. I hope the owners address this issue because the apartment is really nice and at great location.
