Mariana and Carlos's apartment is just as indicated in the posting. Great location (close to all main means of transportation, a commercial area and the nice neighborhood "Belgrano R" with its beautiful parks and coffee houses), very clean and well equipped. Carlos was very kind and flexible regarding check-in and check-out times. I can really recommend this address to any solo-traveler (or couple) wishing to discover Buenos Aires from a less touristy location.
