Victor and Julio José and another person all manage a few units at several properties, yet are super responsive and check in every day or every other day to make sure we got what we needed. They even held our luggage the last day after check out for a few hours before we went to the airport after we asked. They made sure the cleaning lady brought extra toilet paper, towels, etc. whenever we asked.
Their place is well located in terms of transit--you have 3-4 Metrobus lines' stations within a few blocks either direction. It's not that close to Balderas pink line subway station (which we took on the way in from the airport)--we recommend taking Metrobus Line 3/4 (which loop to and from the airport).
Not a knock to our hosts, though the location is close to Alameda Central/Bellas Artes, there's not much going on, nightlife/street vendors, etc. right in the immediate neighborhood (except for the 5 Caudillos bar next door that has live bands every night). We frequently bused or biked to Roma, Condesa, Chapultepec, etc. to find food, coffee, etc. This place has some cookware and a mini-fridge and is decently sized, but you're probably not going to be cooking large amounts of food, since it's so cheap outside.
The building was under construction the whole time we stayed, so there was a lot of broken tile on the floor of the lobby and drywall sanding, which hopefully will be complete in the near future.
Overall, it's a good value and good hospitality for a nice, clean place in El Centro that's not hard to get to other places from.
