The property is a hotel that has been converted for rental through airbnb. It now feels like a hotel without the staff and services offered by an actual hotel. That makes it feel impersonal but that can be attractive if guests are not interested in interacting with their hosts.
It is efficiently run, clean, fairly comfortable (with efficient air conditioning--a must on the hotter days of summer in BA) and in a good, safe location with plenty of good restaurants and stores nearby. The cooking equipment is limited to a kettle and microwave and limited crockery and utensils: no kitchen knives or other implements for example and it would benefit from a few additions.
All in all quite a pleasant place to spend a short stay in Buenos Aires.
