We stayed for 2 nights. We were coming from Montevideo by ferry and Cecilia got in touch with us in advance to make sure we find the way to the location and that the checkin time is okay for us.
The apartment is exactly as you see it in the pictures. It has big windows giving you the possibility to bring a lot of light to the interior. I found it modern, clean and equiped with the basic to assure a pleasant stay.
There are lots of restaurants and coffee shops around the block so we didn't have the need for cooking or using the kitchen almost at all.
The location is quite secure, even entering it late at 01:00 am, we didn't have any problems going out at night.
Cecilia is trully a great hostess, she is very kind and makes sure you have everything you need.
I would definetly reccomend it and would be pleased to book it again when visiting BA.
