My name is Elisa. I am a tour guide who does Off the Beaten Path tours in Buenos Aires. I read your blog and thought that you might like to take a look at my tours.

My tours are also listed on the Vayable website and they are listed first because they are the most popular ones. The company offers more than fifty tours in Buenos Aires.

It seems that you are someone who likes to see non-touristic places and perhaps your audience does to. If you would like to hyperlink my website https://baoffthebeatenpathtours.wordpress.com/ perhaps it will offer and interesting alternative to your readers.

Thank you!
