The accommodation is perfect for one or two persons. There was a little lack of equipment for the kitchen so I bought some (as I stayed 3 months in the apartment). There are washing machines available near the stairs on the 6th and 8th floor. The only downside is that there is a vis-à-vis with the neighbors from the two windows.
The 24-hour concierge service makes me feel safe at all times.
Mariana is always very responsive and attentive, she resolved problems quickly. The flexible arrival and departure really helped me!
The location near the Retiro station is very convenient for catching buses but the area is rather quiet and not very lively (especially if you want to go out at night). There is a small Jumbo supermarket in front of the building and a larger Disco supermarket 5 minutes away. Very good stay overall !
