We absolutely loved Fabian's apartment and would recommend it to anyone who wants to stay in a truly authentic, Argentine home. There are many tall, modern apartment buildings in BA available, but Fabian's place is a unique work of architecture that features marble staircases, high ceilings and doors, hardwood floors, and elegant windows. We really felt the local flavor here, like living in our own home in BA, not in a hotel-like apt, especially given what a charming, bohemian neighborhood Palermo Soho is (also quite close to the metro if needed).
Fabian is a great host and was very flexible with check-in times. He responds quite quickly and he speaks perfect English for those who don't speak Spanish. Fabian gave great recommendations for local restaurants, supermarkets, and shops - his guidebook is quite helpful and we had one of the best meals of our entire trip here thanks to Fabian.
The apartment was perfectly clean and stocked with fresh towels. Wifi worked great for me - had to hold several work calls over the internet and they went just fine. And for the hottest days during our stay, the Air Conditioning worked well and helped provide additional comfort.
