me and my friend both stayed at marcos place,here are our seperate reviews
cLaY:

El Oax is worth a lot more than Marco charges. It's a cool and huge condo that is almost brand new. El Oax is perfectly decorated with cool art and books in a very streamlined way.

The kitchen has all new appliances and the refrigerator has an ice maker and filtered water. There are pots & pans if you want to cook and a blender if you want to make a smoothie. There is even a stackable washer and dryer for laundry.

The guest bedroom is quiet and the bed is comfy. I got good sleep there.
Also there was a TV and play station and basic plus cable.

The location is superb. It's in the middle of the Roma Norte/ Condesa restaurant district. And I felt safe to walk at all hours of the day and night.

It's also close to the Glorieta de Insurgents so you can hop on the express metro bus to go to UNAM or the subway to go to the Pyramid of the Sun.

There are a million things to do in DF, and staying in Marco's cool place is definitely one of them!

El Oax is like a 5 star condo. Everything is new and clean and well designed.

Oh, and there is a totally private rooftop patio that has awesome views of downtown buildings and gives you double the space in a city where personal space is a premium.

I stayed in the master suite and had my own king sized bed, bathroom, shower, chest of drawers and closet space.

The sheets were soft and the bed was top quality. I slept like a baby.

The living room has great light and elegant furnishings. There was also Netflix and I got to watch the movie Frida after going to her actual house, La Casa Azul.

El Oax is a perfect place to regroup and relax after a busy day in a city teaming with 25 million people.

The surrounding neighborhoods seemed safe and kind of posh. The doorman was cool and it made a safe area feel even more secure at night.

Marco is a great host. He arranged a driver to take me to the airport for an early flight.

And he made himself available to answer any questions that came up about things to do and places to eat.

The experience with Marco and El Oax was one of the best things about my trip to DF.

El Oax is a quality place in a central location. It is a safe situation in a new building, and Marco is a sincere host and a cool ambassador for México.
