Abraham's house is really pretty and Abraham and his family were super nice, friendly and helpful! Abraham gave me great tips on where to visit and where to buy my favorite fruit guayaba (guava)! It is not super close to the square, but it's only about 20 minutes walk. And the walk itself is quite interesting. You would pass the park in front of the Fine Arts Museum, where you can see a lot of locals hanging out. And it is easy to access through the subway system. I highly recommend this place for stay!!
