I enjoyed walking through the streets of Montevideo even though they were pretty much empty on a Sunday. The city is a little dirty but I felt safe and liked walking to see the main highlights of the city.
Ciudad Vieja - the old town of Montevideo is really pretty, architecturally unique, and interesting to walk through
Plaza Independencia and Artigas Mausoleum - the large main square and a really interesting burial site of one of Uruguay's early heroes
Puerta de la Ciudadela - what is left of the original wall around the city
The official currency is the Uruguayan peso, but I had no problem paying with my credit cards everywhere that I went.
I walked in Montevideo and used Uber when I needed to go to the airport.
I took a Buquebus ferry from Buenos Aires Puerto Madero to Montevideo Puerto de Montevideo. I flew Amaszonas from Montevideo (MVD) to Asuncion (ASU).
I had a great steak at a place called El Palenque in the fresh meat market Mercado Del Puerto. Even if you don't eat there it is a cool place to just walk through.
PLUGS / ADAPTERS
Uruguay uses European type C, F, and L plugs.
None for U.S. citizens.
I felt pretty safe in Montevideo. Since it was a Sunday the streets were pretty empty, but no one bothered me and I felt safe walking around. I think Montevideo has really stepped up their security recently and I felt safe walking by myself.
SHOULD YOU VISIT?
Maybe? Montevideo is fine (if dog poop on the streets does not bother you) but I don't know if I would plan a trip here for fun. There is not a ton to see, and there are much more interesting places to see in South America. I enjoyed walking through the city but I saw all of the main highlights in approximately two hours, so there just is not a lot to see, at least in Montevideo.
