Arbe is a great hostess, she will give you all you need to know to live in city you dont know. The apartment is big and has every thing you need to be confortable, principally if you are planning a long stay because the kitchen is entirely equipped so you can cook and use the big refrigirator.
The location is unsurpassable, walking distance of most of the touristic points of the city, near to supermarkets and hundreds of restaurants and stores, you feel safe walking around the neighborhood.
In my experience I highlly recomend Arbe´s place.
