We had a great stay. The studio looks just like it does on the pictures - light and stylishly decorated. There is air conditioning, which we used when we visited at the end of March, as it was still quite hot in Buenos Aires. The WiFi worked very well. We enjoyed the sun loungers and the small soaking pool on the fourth floor, which get a lot of sun in the morning but is in the shade in the afternoon. There is a slightly bigger pool and a roof terrace on the tenth floor, which I think gets more sun in the afternoon. We were in walking distance of all the bars and restaurants in Palermo. The closest SUBE stop is about a 10 minute walk.
Ezequiel was a great host, very communicative and friendly. I would definitely recommend staying here.
