The apartment was perfect for the two nights the three of us we were staying in Buenos Aires. Iván was very accommodating with check-in and check-out times, he met us at the apartment and showed and explained everything. There are all lot of small details that have been thought of - like adaptors for the outlets, outlets that work for European chargers, a washing machine that actually worked (not always the case in BA :)) and even mate :) We felt very welcome and safe. The location is great if you are staying in Palermo. The communication was also great, both before and during our stay.
