Guillermo and his wife were very hospitable and welcoming. They even let me stay a few extra hours after check out because my flight was leaving late. Fortunately the next guest was also arriving later in the evening.
This is an interesting place. It used to be a doctor's house (or something like that) and has a bunch of rooms with small private kitchens. I stayed in the smallest room with a balcony and did not have the same setup, so I can only speak for the odd room in the house...
Overall it was comfortable and met my needs. It was pretty quiet during my 3 night stay (other than street noise during traffic hours, which is normal if you're used to an urban lifestyle). Rarely saw anyone, that was nice after lots of travel and activities.
They have filtered water in the main kitchen and offer coin operated laundry in the basement. I didn't realize they took coins and didn't have any. The owner was nice enough to give me some coins to wash and dry my clothes, which was certainly appreciated. WiFi worked fine.
True travelers will appreciate this place for its affordability, simplicity and uncrowded environment. It's very close to nightlife and accessible via a nearby metro rail. Pretty decent upkeep with 4 shared bathrooms. A few of them were often unused, two have showers. No frills, best bang for your buck...
