We had a great stay at Danny's apartment, which, while small, has everything you would need for a short stay in BA. It's close to Recoleta and other centres and is surprisingly quiet for such a central location. The ("historic") lift packed up while we were there, but Danny thoughtfully came to help us with our bags when we left -- and also booked the taxi for us to the airport. The whole experience was easy and fun -- and relaxing.
