I had an absolutely fantastic time at Marinas apartment! It had absolutely everything I needed and more, the washing machine was a welcome plus as was the Subte card Marina graciously provides. I arrived really late at night due to a delayed flight, but still was able to check in without a hitch - and Marina even provided some breakfast items.
I felt very much at home and also very secure during my stay. The apartment is great for a single traveler or for two.
The location is great - lots of great bars and restaurants nearby, also some really nice green spaces nearby - and if you want to get downtown, the Subte is only a couple minutes away. So, if you are considering staying - do so without hesitation, you will not regret it.
