We had originally booked to stay in the studio at Jacaranda for 6 nights but we ended up staying for 8. The location is superb, in Palmero Soho with countless great restaurants and bars within minutes walk. The subway station is 15 minutes walk, in BA taxis are cheap and plentiful so getting anywhere further afield really isn't an issue.
The jewel in Jacaranda's crown really is Lilian who made our stay in BA perfect. She was on hand almost 24/7 I answer questions, give advice and to help with bookings and giving hints on cultural events.
Utterly fab place to stay, couldn't reccommend it highly enough.
