I was very pleased to find that the accommodation was better than I expected. Everything was great and the location could not be better. It was a little noisy with parties etc but that's the nightlife in Buenos Aires. I don't think you can find a better place than San Telmo. As long as you are sensible, it is perfectly safe with lots of antiques, restaurants and cafes. There is so much to see in BA and, of course, great for tango classes. I am hoping to return and stay with Carolina again!
