We had a fantastic stay at Montserrat's apartment in Zona Rosa! The apartment was as cute as pictured and amazingly clean. We could walk to a ton of amazing restaurants, bars, and sights from here. Everyone who works in the building were friendly and helpful, too. As others have mentioned, the bars and clubs downstairs do get pretty loud, but if you use some of the earplugs provided and turn on the fan, you can't hear any of it. Also the bed was incredibly comfortable—best sheets ever!
