We had a great time at Ana Maria's place. Both her an her husband were very open to help with anything and very tohughtful.
The neighborhood was incredibly quiet (at least in July) and very well connected to the most well known places in the city.
Being a separate place makes it a very comfortable option to have complete privacy.
The only problem we had was the WIFI not working very well. Nothing too bad unless you rely a lot on it to work during your stay.
