We had a wonderful time staying in San Telmo at Arlans place.
The apartment is beautiful the rooftop terrace easily could host a football match and the area is superb. Just in the middle of San Telmo. When you step out the huge wooden door on the street you're in the middle of all the fuss.
We stayed in the apartment with 7 people and it could easily host us all.
Graciela, the neighbor and housekeeper was very helpful with every problem that occurred.
Altogether we had a very fun time in Buenos Aires with the apartment being one of the main attractions. If you need a place to stay, Arlan should definitely be your number one choice.
