Probably one of the most alive neighborhoods, San Telmo is the perfect place to stay while in BA.
To set your expectations, to me San Telmo is the best place for people watch, to have a drink and get lost around locals. Here some of the things I could list for you to check out.
Mercado de San Telmo
Maybe one of the most popular activities is the Mercado de San Telmo. Packed with restaurants, it can get overcrowded especially on a Sunday.
The interior looks something like:
Sunday's
The party is taken outside. If you don't have the accommodation in San Telmo, make sure you pass by on Sunday to explore the merchants selling different souvenirs and people dancing around the streets
a bit of architecture
Milongas
If you want to practice some tango or simply watch, a milonga is the cheapest option you have on hand. It's usually held either in a bar or simply in a square. Get yourself a partner if you know the steps and join the other dancers
StreetArt
I found a few cute corners with streetart. It's nothing fancy, but worth the picture :)
The Hotel
We stayed at Circus Hotel & Hostel in San Telmo. I had loads of mixed feelings about this place. To be totally honest I would not stay there again, but at the time when we went it was best quality price offer.

If you go there for NYE, they organize a BBQ and some confetti. But the food, although very good, for sure not enough for everyone so keep that in mind if you opt for it.
Food
I know this is self explanatory but with all the distractions around i would prefer to make sure you grab something to eat.
Breakfast
We gave the breakfast @Le Ble a try, good food, but it was super slow.
We also tried Casa Telma, food was great, service was great. can only recommend.
Argentinian Pizza
It was highly recommend to try the Argentinian pizza, so we asked our hotel and they recommended La Moderna. I checked some reviews which seemed great, we gave it a try. It's not bad at all, but don;t expect anything similar to the Italian pizza (otherwise you might be disappointed)
Dinner
After a bit over 2 weeks in Argentina we thought to give some different food a try, and we ended up in a Colombian bar (Cartagena). We all had loads of fun over there & we loved the food and the people working there.
