The good: this apartment is in an EXCELLENT location! It's steps away from both Metro and bus lines in a very safe neighborhood with great places to eat. Also very close to the park. The not-so-good: the street noise in the apartment is really, really loud and it goes on most of the night. There are the conversations from the diners below that can be heard word for word, and the cars and buses, plus the garbage and recycling trucks that pick up trash early in the morning. Even with earplugs, it was very loud. I've stayed in Air B&B's in other major cities in the US and Europe and haven't noticed this kind of noise before. It may be that this is common in Madrid, but it's more than I've noticed elsewhere.
