Everything was great! Our flights were changed and we didn't get into the city until 2am and Eduardo was very flexible to our special needs and was more than accommodating. We felt safe at his location with the watchman and enjoyed being close to the downtown and tourist areas. The stairs up to the 5th floor were a challenge on those days when we had done a lot of walking, but I knew that this was part of our stay at his place. Keep in mind that in Mexico the 5th floor is technically the 6th floor as there is a ground level. Also, keep in mind that during July there are rainstorms, so be prepared.
FYI, there is a laundry mat located around the corner that does full service and will have your clothes ready within 24 hours. There are some great little food joints in the area especially on Ave. Niños Heroes located two blocks to the west. I recommend a walk over to the Balderas metro station for some great food, but on Saturday's there are two groups that take over the park there. One is a group of dance instructors that teach and have open practices for any age and genre. Also, there are Hot Wheels and toy vendors for anyone who enjoys collecting or if you have children.
