The apartment is great if you are by yourself, or a couple that just needs a place to crash and enjoy the city. Marcos describes the apartment as it is...simple but has most of amenities you need for a short stay. Very close to the metro and beach within walking distance. The building staff is also very helpful and nice. Because it is located close to a slum, some people think it's a dangerous area, but it's the price of being in a big city... I didn't have any problems and in fact some of the staff would stand outside with me if I was waiting for an Uber. The minor issues I had in the apartment were fixed right away and the communication with Marcos and his wife were very fast. They even sent one of the doorman to check the TV that wasn't working ( in fact it was the remote control).
Because I've been on the hospitality field for years, I suggested them few things to do here and there to better accommodate their clients and they took it very nicely. The price is very reasonable for the location. They also made it very easy for me to check in and check out, just so I could adjust my schedule. I totally recommend them.
