I had a great stay with Pedro and Joanna - it felt like staying with friends and this is what Airbnb is all about for me.
The flat is light and spacious, with fast internet and two bathrooms. The bed was comfortable, the bedding and towels were brand new and checkin was easy. There are shops and the excellent Mesa 325 cafe nearby, a Metro station two minutes away and it's only a short walk into the city.
