We had a wonderful stay at the Brit in Mexico City.
The front desk staff were lovely, the security/doormen were all very friendly and helpful.
The location was fantastic for us- we walked to Chapultepec Park almost daily (about 20 min walk if your fast). There are many interesting things within walking distance and Uber was very cheap for farther distances. We walked to Condesa, Hipódromo, Roma, and all areas of the park with no issues. We always felt safe in the Juarez area and nearby- night and day.
The apartment was very clean and modern. The bedding was very soft and the bed was very firm, which we like. The washroom is on the small side but means extra room in the apartment, which felt very spacious.
The wifi is excellent and there are 2 TVs which have many streaming sites available for you.
The area is lively with lots of things happening around. If you are sensitive to noise I would recommend earplugs but we are from the city and the city noise is comforting to us.
We highly recommend eating at Pacifico for breakfast and lunch, trying Tacos deli for gringas and Maque if you are looking for something higher end.
We stayed for 8 days and my only feedback is that we would have liked to have more coffee, towels, toilet paper etc.. just for our longer stay. Although those were easily supplied by our host once requested.
