Our hotel was the Jardin del Iguazu. It is a small hotel with maybe 30 rooms but it is very nice. Simple, but nice. The rooms are on two stories surrounding two beautiful courtyards. One courtyard has a fountain and one has a small pool which features backlit waterfalls.
We entered the lobby and were checked in by a young lady who wasn't sure what to charge us as our confirmation didn't have a rate on it and we booked nearly 11 months ago. She called the manager who came down and asked us if it would be ok if they gave a 10% discount off of the current rates on the website. We thought that fair and accepted. (2 nights = $1000 pesos = roughly $231 dollars for two nights in high season. Sure beats the $300+ the Sheraton wanted from us, per night!
At this point my wife was starving and I never am one to skip food so we asked the staff where they go for good takeout, with a proviso, we needed someplace that served vegetarian options. The manager, a very funny middle-aged man asked us who the vegetarian was and I dutifully pointed to my wife and said that I eat everything.
The manager, a very kind middle-aged man then told my wife that he worked in a slaughterhouse for 20 years and couldn't imagine not eating beef and he then extolled the virtues of Argentine beef. A man after my heart, after all, I can't imagine not eating beef either! He ended his good-natured lecture with a laugh, and two alcoholic welcome drinks ! and they sent us two blocks down the street to Misiones an awesome empanadas, coxinha and pizza place.
My wife ordered 2 cheese empanadas, I ordered two coxinhas con carne (a fried potato stuffed with beef). I got a coke, she a water and the grand total came to $26 pesos or $6 US. The food lived up to its billing, we enjoyed our meal at a table overlooking one of the courtyards before heading to bed.
A quick note on our room. We had a standard double which consisted of two single beds pushed together. We had a 24" flatscreen and great air conditioning. The bathroom was sizable with a stand-up shower, bidet and toilet. The room as mentioned above was simple but very very clean.
We were in bed by 11pm Iguazu time or 9pm Washington time and slept very well.
