The apartment was really lovely, clean, well equipped and in a great location walkable to public transport and the major sites that Buenos Aires has to offer.
The best part of our experience however was Gustavo, who went well beyond the duties as a host. From the start, he was extremely responsive to questions and gave us many local tips about the area. On the final day of our stay, when our flight was cancelled, he offered to let us crash out for the night at another apartment he had available at no cost, and then arranged two taxis which promptly arrived to get us to the airport (not so simple because we had two large bike containers in addition to regular luggage, and most taxi drivers we had contacted didn't want to take the bikes). This is hospitality at its best, and we are so grateful for all of his help and hospitality. Gustavo - muchas muchas gracias! If you are in Seattle, please don't hesitate to look us up :-)
