Sandro and Lalo were both extremely responsive and helpful from the moment we booked Sandro's apartment.
The apartment itself is very well located and peaceful (amazing in a city so big!). Our experience was enhanced by Lalo's hospitality - greeting us on arrival, sharing recommendations on local restaurants and even dropping us at the airport (as he was already going that way).
In short, this is a great apartment in a prime location with exceptionally helpful and professional hosts. I highly recommend this apartment!
