We had largely pleasant stay. The breakfast was very good and although you were asked to book in for a 45 minute time slot, the staff still had difficulty keeping the buffet supplied. That meant that you could arrive and find there were no cleared tables nor was there food available if you didn't want something sweet.
The swimming pool area was very nice and there were tables outside there where you could eat if the weather was pleasant.
The staff spoke English and were helpful. The location is very good for walking and also is right close to the ticket office for the hop on hop off bus. If you have cash buy your tickets there.
For us the major downside was that we had specifically chosen the 'Pay the Hotel' option in Expedia when we booked only to discover that our credit card had been charged as soon as we booked.
When we went down to pay the night before we were leaving (we had a early morning flight) we were told what had happened. We showed them the reservation booking that clearly said we were to pay at the hotel and they acknowledged that it was their mistake however, for reasons that we cannot understand it was apparently simply impossible for them to reverse the charges and let us pay in cash. This effectively doubled our cost of the stay because of the exchange rate system in Argentina. We contacted Expedia and they were NO help and their site still says you can pay at the hotel.
Buyer Beware. Two bottles of wine were not sufficient compensation for this mistake.
