Karen's place is located in a very safe area of the city which is very accessible to many points of interest. If you are early to rise and want to get the most out of your day, this is a great place to start from. However, if you like to sleep in on the weekdays, there is a bit of city noise that is typical with any big city, contrasted with the weekend which was bit more quiet. Coming home to Karen's place after walking around seeing the sites all day, it was great to sit on the roof patio and look out at the cityscape around the neighborhood.
The kitchen was well stocked with proper utensils and cookware, making it easy for anyone who wants to cook. I have food allergies so I ended up cooking quite a bit and found the accommodations to be very easy to deal with. There are a few grocery stores in the areas which made it easy to eat while on vacation. There are also a few allergy-safe / gluten free restaurants and bakeries in the Roma Norte neighborhood to the south if you are interested in that.
Lastly, Karen's apartment was immaculately clean. She is very accommodating and will respond quickly to any request.
