Ivan's studio is a great place to start out in Buenos Aires. It is well located in Palermo with good transport links and night-life nearby.
The studio itself is exactly like in the pictures... spacious and modern, with everything working perfectly. The building is modern and secure.
Communication with Ivan was always smooth, and he responded very quickly to any concerns I had, even though I only met him in person on one occasion.
One minor complaint... there is a lot of construction going on nearby... so if you cherish long lazy lie-ins, then think again!! This however is no fault of Ivan's...I'd recommend the studio anyway!
