We stayed at Villa Santiago the month of January renting the whole place. Initially we were two older couples and for the last two weeks just one. The house is new and built to a grand scale. The owners hope to sell it but in the meantime are listing it on AirBnB. We were met on arrival and shown into the house which was immaculate. The grounds outside are well planted and maintained. The company has a large staff We primarily interacted with the housekeeper (once per week), the night watchman who met our taxi at night and walked us to the door, and the gardener who came 3 times a week to water the plants.
We were familiar with the neighborhood from prior visits. It is about a 15 minute downhill walk to Instituto Allende and Parque Juarez, and 20 minutes to the Zocolo. We always took taxis home at night. There is a tienda nearby for things like milk, rolls and fruit. Restaurants, banks and pharmacies require a longer walk. The view from the rooftop is panoramic - You can see the whole town.
The house has heavy, substantial furnishings. The beds are quite comfortable. Since it has never been lived in it lacks the personal touches and decorations typical in San Miguel. On the other hand there are watercolor paintings everywhere (the theme of Villas Acuarela), many available for purchase. The appliances worked well except for the dishwasher, which apparently needs to be replaced. The WiFi is good, in fact I was able to run an HDMI cable from my computer and watch streaming video from Netflix and YouTube.
In all we had a good stay and would recommend it. One thing that would be helpful would be a manual in English explaining how to use the appliances including the heater, what to do with garbage, etc. The staff was always helpful but there was often a language barrier.
