I enjoyed Carlos is place very much.
Pros:
The place was in a perfect location, beds were comfortable, the apartment was spacious and stocked with essentials. Also Carlos was quick to respond and answered all my questions. We were able to leave our bag with the receptionist (security) after we checked out so we can explore the city before our flight. There is a pharmacy next door and a local oxxo market which is convenient.
Cons:
Noise from above was loud in the evening because we could hear stomping from above. Also if you are sleeping in the room on the right the hallway lights shine into the room at night when somebody roams the main hallway which can be bothersome when you are trying to sleep at night.
Concerns with blinds and privacy in bedrooms. I would nice if they could add a curtain for additional privacy because it felt like people could see us from the outside at night.
