We had a great stay at Pedro's apartment. Great location, we walked pretty much everywhere, and also close (5 mins) from Metro. We loved being able to open the windows and be part of the street life.
As others have noted it is a pretty noisy location at night, and there is a full blown party outside in the streets on a Saturday night! We stayed out late so it didn't bother us too much, but if you plan on early nights it might be an issue. The bars outside stay open until 2am so it doesn't really get quieter until 3am, and then the clean up starts in the morning! The windows are pretty good at shutting out most noise but of course you might want them open when it is hot!
Very well equipped, and the bed is super-comfortable. We had a fantastic stay.
