We had a wonderful stay in Felicity's apartment. We were welcomed by Claudia who showed us everything we needed to know about the apartment, she even organised a pick up for us with an infant car seat to take us to the airport. The apartment is in a great location for exploring Buenos Aires, you can walk everywhere as we did but if your not keen to do this there are taxis, the subway and buses on your doorstep.
There is a small supermarket across the road from the apartment, or a larger one a couple of blocks away.
We also made us of the excellent kitchen during our stay, and the washer and dryer as we have our two year old daughter with us. We will definitely be recommending Felicity's apartment to our friends when they visit Buenos Aires.
