Although my hosts were away on vacation themselves, they ensured by both their immediate response to any queries I had, and delegating their friend Carmen to meet me, that I was well looked after. (The concierge in the building was also very kind).
I cannot speak highly enough about the apartment. The view from the apartment was stunning - looking out over the Las Heras Park. The facilities were all I could wish for, and I felt really at home there.
The location was perfect, both for restaurants and small shops in the streets round about, and for public transport (I used to take a pleasant walk across the park to catch the metro at Bulnes - from where I could go anywhere. Also,there are lots of buses going past the front door).
And, just in case anyone reading this hasn't been there before, Buenos Aires is the most beautiful of cities - especially at this time of year with the Jacaranda trees in blossom. I hope to return one day.
