I highly recommend this place! Having read previous reviews I was a bit sceptical, but let me change your mind because this is a lovely modern and well equipped studio in a fantastic location, with a lovely balcony and an excellent shared solarium/roof terrace on the top floor which has stunning views and lovely sun-loungers to catch some rays! I personally didn't have any difficulty with the check in/check out process, the cleaning lady met me at the apartment and gave me the key, but the key deposit box (which comes up a lot in previous reviews) is really not far away, about a 6 minute walk. The building is very secure and feels very modern and clean. I stayed in 3 airbnbs in Buenos Aires and this was definitely my favourite! Great bathroom, comfortable bed, kitchen has everything you need including a coffee maker. WiFi good for working remotely. Thank you!
