I stayed for 1 month at the Dolores house and I couldn't have felt more at home. I was solo and it was extremely safe and I never had any problems with security. The apartment is in such a great location you can walk just about anywhere and if not Uber is extremely reliable. It is close to Alameda Central which is a beautiful park, La Vasconia the oldest bakery in Mexico City. It's close to shopping, food there's actually a restaurant right across the path. The host is super accommodating and even provided me with purified water (a huge jug) during my stay. Someone comes to clean the apartment once a week and you just really feel cared for here. I was actually very sad to leave because it felt like home. Also I forgot to mention, I taught remotely from this location for about 7 hours a day using 2 computers and didn't have any issues with the wifi so if you're working remotely this place is extremely reliable for that.
