My experience at Anna's was really great, I truly recommend it!
The localization it's perfect, really near of all the main touristic attractions, the bus stop, the subway and lots of cool restaurants.
The place works kind like a hostel, because all the building has rooms and sharing kitchens and bathrooms. It worked really well for me!
I didn't saw Anna much, but she shared with me a bowl of her dinner one night, left with a note on the door of my room. Really sweet!
