Pros - clean, great location, not noisy, spacious room, attentive and friendly staff
Cons - hotel is old and not in great condition, hot water takes a bit to get going
Overall, I liked the hotel. Given the cleanliness, staff, and location, the price was great. Friends of mine stayed at "nicer" hotel a couple of blocks away and couldn't sleep at night because of traffic and street noise and they paid almost three times what I did. I will definitely stay here again when I return to Buenos Aires.
