Amazing apartment!
The location is great, one block (250) away the Belgrano R train station. The train stops in Palermo and ends in Retiro (approximately 15 minutes ride). Within 250 meters you have two mini markets, one of the best fruit- and vegetable stores in entire Buenos Aires, a fishmonger, and a butcher. 5 blocks away you have the metro, a huge shopping street and all the shops and restaurants you want. It's not as lively as Palermo, but it is an amazing neighbourhood. Very nice and upscale.
The apartment is exactly as pictured. Big apartment in two floors with a huge bed and more than enough closet space for even long term stays. I stayed for one month during the coronavirus quanrantine and it was the perfect place to be locked inside. The view of the city is absolutely mesmerising. That alone is worth it all.
And lastly, Sofia is the perfect host. She responded to all my messages within minutes and quickly fixed any problems that arose. I only have my highest recommendations for Sofa and her place.
