Guido's places is wonderful. First is the Location, it's the ideal spot to enjoy all the bars and restaurants Palermo has to offer. Just steps from Plaza Julio Cortázar (aka Serrano), the places is most frequented by a young adult crowd (20s and 30s).
The places has 2 identical bedrooms just like the one in the picture, so it's perfect if you are shearing with another couple. AC in all rooms is a life saver. The living room kitchen space is small, but integrates with the outdoors space. Kitchen has all you need for a short stay and Guido was so kind to leave water and juice in the fridge, coffee and Yerba mate (just in case you want to sip some loca mate).
