Buenos Aires is the most European city in South America. It used to be an entry port for many settlers. Mainly Italiens and Spanish, but alsow German, Polish, Russian etc. went through La Boca (= the mouth), Buenos Aires oldest quarter at the riverside.
Favourite spots:
The quartier La boca today is an area, that is favoured by artists, that live in picturesque houses. Here you can still sense the big Italian influence. Good restaurants!
What's really great:
North of the modern port is a natural reserve area - the best spot to flee the cities stress and pollution. Nice grass-area, that is not visited by too many people.
Accommodations:
Heeps of refugios and cheap stays in San Telmo.
Restaurants:
If you like Italian cuisine. Any restaurant in La Boca.
How about including some photos? Would be nice if you could include some names of specific places to stay that you would recommend from your experience.
