Jose's place is really good. It is super modern, clean, quiet, with all the needed facilities (air co, dishwasher, TV, Netflix, WI-FI etc). It is located 5min walk to the metro, grocery store (giant), stores and restaurants.
The commute to National Mall takes around 20min with metro. Very easy and convenient.
Jose is a great host, very helpful and responsive.
We stayed there for one full week, visiting Washington, and felt like home.
Thank you very much Jose, it was perfect!
