Wow! Victor's place is even more incredible than it looks in the photos!
The room/building itself is so stylish and interesting. The big bed was comfortable; the bathroom was gorgeous (and there was plenty of hot water, although the temperature could be a tad finnicky - not a big deal at all though). We didn't meet Victor, but Julio and Marijose were so nice and helpful. We only stayed a few days and didn't need much, but it was great knowing they were around if we needed anything.
We also loved the neighborhood. We had been in Condesa for about a week beforehand, which is convenient but very touristy. Colonia Santa Maria la Ribera feels much more authentic and neighborhood-y. There are still plenty of great restaurants and bars within walking distance, and the metro is only about half a mile away, so it's still very convenient.
In short, stay here! We definitely will be back!
