We stayed 5 days at Sergio's place. Apartment is centrally located and we walked to most of the landmarks. Metro station Tribunal is few minutes away.
30 minutes by metro from the airport.
There is plenty of restaurants and supermarkets around.
Having A/C is a great plus.
I have no complains and would certainly stay again.
Andres was very responsive to our questions and checked on us during our stay. Great host, great place, highly recommended!!!!!!!
