We go often to Buenos Aires. I would not choose to stay in the San Telmo Area. Instead I would stay in the area near to Patio Bullrich (this is a stylish small mall in Barrio Norte) or in the Recoleta area which is nearby. Usually we stay in hotels but last year we stayed a full month in an apartment near Patio Bullrich and loved the location. We paid 850 dollars per month. This was an apartment with maid service everyday of the week, change of towels everyday, and bed linens I believe once a week. In essence it was a big one room with a tiny separated kitchenette and a good bathroom. Cable. And 24 hour security, with a front desk taking messages.Phone was extra but was very inexpensive. Be sure you get an apartment with 24 hours security. Furniture was ok nothing fancy, it had one big plus - it was on the sixth floor facing a huge garden that belongs to the Embassy of the Holy See and one minus - bed was queen and was in a corner of the same big one room.

If you think you might like something like that I can look for the number. The owner was a very nice guy. IT could be rented at 50 dollars per day, all inclusive but the hone. Buenos Aires is full of cafes, restaurants, and the like. Also if you rent there are many options of food delivery, like sushi, pizza, etc. if one day you do not wish to go out. You can ask for daily newspaper delivery which I Highly recommend, the Buenos Aires Herald is a good English newspaper. The apartment is not exactly adequate for cooking a full meal, but of course is ok to heat a soup, or a tea, it has a small fridge, pot, pans etc. Around the corner there is a good laundry, dry cleaner. Another thing, taxis and radio taxis are abundant, excellent and inexpensive. Taxis can be flagged in the street but I believe it is safer for tourists to call them on the phone.

There are many good and rather inexpensive hotels which can be an option too.
