Everything was perfect -- with the apartment, the building, and the neighborhood!
My stay was almost two months long, and the apartment was well equipped with everything you'd ever need. The check-in and check-out processes went very smoothly.
The loft-style layout, with its two floors and staircase, really set it apart from the usual apartment or hotel room. After a long day, it was nice to come back to the apartment and relax on the terrace (off the living room) or on the smaller balcony (off the bedroom upstairs). The round-the-clock doormen downstairs were friendly and professional.
The neighborhood was residential and quiet, while also feeling very safe at night. Within only 1 or 2 blocks were a huge supermarket, a full-service laundry/dry cleaners, various cafes & restaurants, a pizzeria, an ice-cream shop, a park with a jogging path -- pretty much everything.
Most importantly, Sergio and Mirna and their whole team were helpful, courteous, and bilingual. No random issue came up during my stay, whether large or small. However, if something had come up, I'm sure they would have handled it and solved it quickly and thoroughly.
I would definitely stay at this property and with this host again -- and, whenever I'm back in BA, I probably will!
