Trip to Buenos Aires

Last year my wife and I went to Buenos Aires, Argentina and we loved it there. It's a wonderful place with very nice people and amazing cafes. We were in a hotel next to Florida Street, which is one of the most important commercial centers in Buenos Aires. We visited a lot of place during the 5 days that we spent there. We went to the zoo in Lujan, a city very close to the capital. It's an unbelievable experience, because the animals at that zoo roam free. We can walk into the cages and enclosures and stay with lions, tigers, elephants, bears, enormous snakes, birds and other savage species. We were able to pet little lion puppies and take fantastic photos.
We took a tourist bus in Buenos Aires that took us to the main touristic places of the town. La Bombonera, a soccer stadium, the planetarium, a lot of green and very pretty squares, the casino, the metropolitan cathedral, and very other welcoming places.
That's a place where we will certainly will back! If you don't know it, I recommend that you go some time.  Have you ever been there? What place did you like a most? How is my English? Help me to improve.Thanks.
