Absolutely outstanding.
First of all, the apartment is beautiful, very well equipped, and extremely clean. Great furniture, appliances, TV, etc etc.
The location is phenomenal, just in the heart of Puerto Madero, the safest and highest-end area of Buenos Aires.
The host, Ignacio, was lovely and helpful. Got a great deal of suggestions from him and he also took care of my luggage after the check-out.
He even sent me a message afterward to check that everything was perfect.
I definetely reccomend this place. Will be coming back
