We stayed for a few days in Buenos Aires, it was our fist time there.
Jonathan is a very friendly host. Even we came more than an hour to late to the appartment, he still waited for us to give us the keys.
Afterwards he sent us many many tips for things to do in Buenos Aires.
Also the checkout was very easy and comfortable, so we didn't had to worry about anything during our stay.
PS: The best was maybe the free bottle of wine, we opened immediatley after our stressful arrival ;) Thank you, we enjoyed our stay very much.
