Though not met by the host, his mother was extremely welcoming and provided a lot of practical advice. The apartment was ideal for 2 people; stylish, warm, well equipped and ideally located. Palermo is very accessible by metro to the city centre, with loads of cafes, restaurants, bars, shopping and attractions within walking distance. Buenos Aires only wakes up at 10-11 pm and it could be a bit noisy on weekend nights, but not enough to take the gloss off a great place and would stay again.
