I stayed here for a week with some friends and the place was PERFECT!!
Thierry is a great host and the apartment itself is really modern, spacious and has everything you need. The complex it's in has excellent amenities as well ie. large pool and great outdoor spaces, gym, spa, secure underground parking etc all maintained by really nice staff.
Really good location too, just quick (cheap) cab ride to anywhere and 15 min walk to the heart of San Telmo or La Boca.
Thanks for a great stay!
