Diego‘s place is great! It was our first time in Buenos Aires so we appreciated not only the jaw dropping view of the city from the 19th floor, but also a super central location. You could get a cab to all tourist attentions within 20 min, and walk to the closer ones without any issues. The place has everything one can ask for. The building is well guarded and quiet. There are plenty of shops, bars and restaurants around. Highly recommend!
