Dear Emma, PR-25R (Ave. Muñoz Rivera) is a two-lane main street into San Juan, but not a highway. It runs parallel to the new boardwalk designed for pedestrians and bicycles and features beaches, parks, restaurants and historic buildings (the Capitol building among them), connecting Condado with Old San Juan. I mention the street noise in the description of the apartment. As also described in the ad, the apartment works with cross ventilation/Ocean breeze and five ceiling ventilators. The additional pedestal fan just broke down before you came and the new one I bought turned out not to be satisfactory. I just returned it and will place another floor fan in the apartment for more comfort during the summer months. I'm sorry you felt hot, but am glad you otherwise enjoyed your stay! Thank you.
