Louis's apartment is pretty, clean, and incredibly convenient. The courtyard gives the place some extra light and a lovely place to drink coffee. The beds are comfortable, the kitchen is well-appointed—not that you'll need to cook!
A park up the street brings together restaurants and coffee shops around its border. We were able to walk to museums, and to fantastic food.
Louis gave us excellent recommendations for dining and activities, helpful tips for getting around, and even called us a cab for the airport (because I had lost confidence in my Spanish on the phone).
All in all, it was a lovely stay. I hope we return soon.
