We are staying there and wonder if you can tell us what to do or not to do. Thanks

Well, according to http://tinyurl.com/yaoa5zd one thing you should do is watch their price list before ordering.

If you are asking about activities in BA, there are many trip reports in this forum which may give you ideas, among which you can choose, depending on your taste.

Then, you could ask more specific questions.

Have a great time in our country.

The Cementerio de la Recoleta and Museum of National Arts are in the immediate area.

Check in with a very heavy wallet...

Right down the street (exit right), on Posadas, is El Sanjuanino. One of the top empanda spots in BAires. We think its about the best ones we have had there. Its well known. Inexpensive, sit down lunch. For us it is a mandatory stop. Have fun.

And right beyond El Sanjuanino is Fervor, an excellent grill. Around the corner from Fervor is Sottovoce, a highly rated for Italian. All wonderful dining options.

I absolutely agree! El Sanjuanino offers great regional dishes and Sottovocce (Italian) and Fervor (grilled fish) are both wonderful dining options. All these places are within walking distance of your hotel, as said above.

Have a great time in our town.

don't miss El S...!!!
