The apartment is impeccably clean and well presented. Everything you need is there. The location of the apartment is perfect if you need to get around town as there are many buses that go all over Buenos Aires. Or you can just hang around the neighbourhood in the bars and restaurants or get your own food from the nearby supermarket.
The communication between Sandra, Agustina and myself was faultless. They always responded quickly and answered my questions. Receiving and returning the keys was no problem.
All in all, a perfect stay in San Telmo.
