Great staff, particularly Constanta, who loaned us a Sube card for the duration, which gave us cheap fares.
Location is excellent, (on Plaza Dirriega which has great atmosphere from 10am to 10pm - we even saw Tango dancers on Saturday morning, but Sunday has a big market). We had no problems walking around the local area - went to a Millonga about 500 meters away at 10pm and walked back after midnight, admittedly along well-lit streets.
The only gripe was the bad drain smell in the room as soon as you enter, (but do not notice it after a few minutes).
breakfast was very nice.
It was also about 15 minutes walk to the metro, which could be a chore after a long day, but taxis were cheap.
A real problem with Argentina that I did not appreciate is the really expensive ATMs that can charge over 400 pesos for withdrawing 2000. They have a limit and I was never able to get more than 3000 pesos and that was only once.
strongly suggest you bring the cash you will need.
