We stayed for 2 weeks, and in general had a very good stay and would recommend the place. The appartment was big, 2 bedrooms, had very good quantity and quality of supplies (unlike some Airbnbs that use cheapest towels, toilet paper, don't have shower gel etc, Fernando's place was very well equiped). The one thing that missed (a iron and iron board) were promptly arranged by Fernando, who was very responsive during the entire stay as well as asking regularly if all was ok.
As we stayed in coldest month -jan, it was good that there were ample blankets, and even portable heater which was really needed in some nights.
The location is very good, right in business district with many restaurants, coffee shops etc closeby, as well as close to the main park.
We did find the pictures a lot brigher than actual, as there is no direct sunlight, which is not uncommon in Mexico.
Also the main bed was a bit too firm and smaller than looked on pictures, but for most people <1.80m will be just fine
