Pros: very secure, relatively quiet, OK Internet, Miguel is a nice guy.
Cons: filthy (needed 5-10 hours deep cleaning and a paint job), $30/night is a poor value (my subsequent place was cheaper, in a better part of Roma, and ten times nicer). Lots of outdoor containers of standing water breeding mosquitoes.
Miguel should not list a washing machine as included in the rental, as the unit is this weird antique non-automatic thing that you'd never want to use. The lady across the street who I paid to do my laundry didn't sufficiently rinse the detergent out of my clothes.
