Just as nice as could possibly be. Great neighborhood, great hosts, great apartment. Perfectly well equipped. When I had a problem (my fault, but whatever) the hosts immediately responded to help me out. So you can count on them for sure. Sometimes there was some street noise. It's very low traffic street, but there's lot's of people walking around, some businesses, etc... basically, city sounds. If that bothers you, you probably shouldn't visit Mexico City. Point is, this apartment would be great for a few days, but if I needed to stay for months I would be totally comfortable here. It's a home.
