First off, the location is just the best. Sol is known as kilometer zero for a reason, it's in the middle of everything! And Vallita's place is just a short block away from the Metro and train stations. The place is clean and accurate and although you'll be staying at a busy area, you won't hear any noise! Her family was warm and welcoming. You'll be sharing the bathroom but during my 4 night stay I never had any issue whatsoever. I highly recommend!
