Eugenia and Luis's place is great! It's a building that has been converted to an Airbnb so most of the people that stay in the building, if not all, are tourists.
It is close to the Metro and everything seems to be walking distance. There are lots of restaurants nearby too. It is by a main road, but it wasn't that noisy at all.
It is a plus that they give you fresh bread in the morning and that they can store your luggage after check out (during weekdays only). We won't hesitate coming back.
