Lorena's place is a great value proposition. Not only very well priced, but it has everything you need to make your stay enjoyable. It is really well located, in a very nice and upscale neighborhood and within walking distance to subway and many bus lines. The apartment itself is really nice, spacious and very clean.
As far as the host, you could not ask for a better host than Lorena. She is extremely friendly and goes the extra mile to make you feel at home. She was waiting for me with coffee and snacks and checked with me throughout my stay to make sure everything was OK.
She absolutely represents the spirit of airbnb, where you go to rent a place and leave with a new friend.
