Sarah's place is a great value! It was perfect for a place to crash after a long day of exploring and within walking distance to downtown/the central district. Also, it was a short uber ride to other neighborhoods (like Polanco, Roma Norte, etc). There were enough amenities if we wanted to prepare meals at home, including a microwave, fridge, kettle, and hot plates. As other reviews have noted, you do have to climb a ladder to reach the bedroom, and a flight of stairs to reach the unit itself, so would not recommend it if you have mobility issues. We really enjoyed access to laundry, the beautiful rooftop terrace, and the cafe and nail salons within the building itself! Wifi was also accessible and there were several places outside of the unit to work as well.
We did have an issue with checking in, however. Our flight arrived in the evening, past when the security guard was there who could have otherwise let us in. Unfortunately, the codes Sarah gave us to enter the building were incorrect, but thankfully there was someone inside who let us in, helped us find the unit, and called Sarah and gave us the key that she left at the front desk. Later we found it is was an accident and her message explaining instructions further did not send, but it was a stressful 15 minutes! Would recommend just making sure you have all of the check-in information ahead of time. Other than that, we enjoyed our stay!
