The apartment was in a nice and convenient location, very clean and spacious. The bed was very comfortable. The only issue was that there was no extra toilet paper and the hot water in the shower kept going on and off. But Martin had shown how to get the hot water back on when it gets cold so it was fine.
On my day of departure, it was raining hard, and in Buenos Aires, it's difficult to get a taxi on a rainy day, even if you request one by phone. Martin's father was so kind to walk out and help me hail down a taxi in the rain and tell the driver in Spanish where to go.
