If you're considering coming to Buenos Aires, I highly recommend spending some time in Palermo and this apartment is a great deal considering it's ideal location. It's very clean and furnished with everything you could need for a comfortable stay in Buenos Aires. Both Diego and Martha are wonderful- They both speak english and Diego responds to questions quickly and is a very helpful host.
There are several busses that stop on the corner that will take you anywhere you may want to go, and Plaza Italia where the D line of the subte stops is only 10 or so blocks away. It's also very easy to catch a cab on the corner if you don't mind spending a bit more on transportation.
The neighborhood is packed with hip bars (check out thames 878), amazing restaurants, and cute shops- and it's also very safe! There are several grocery stores very close by, as well as a drop off/pick up laundramat very close as well. In fact, during my stay Martha bought clean towels and sheets each week, and even dropped my laundry off for me as well.
