It was wonderfull to stay in this appartment. Flor and her husband Nicolas were very helpfull. The neighbourhood is quiet (compared to the centre of the city) and full of nice trees hanging over the streets. You're 10 minutes walk from nice restaurants and shops, a little map of this is available in the appartment. For the highlights of the city you have to travel a little further by bus or metro. But if you fancy dancing tango and going to milonga you are in the right spot. They are very close. I would absolutely recommend this appartment if you want to have the feeling of being a local in BsAs and still have all the comfort you need.
By the way, Nicolas arranged a taxi for me back to the airport which was very helpfull and convenient and gave me a feeling of going home safely.
