10/10 would stay again. I stayed as a solo traveler and had a great stay at Gonzalo's. The apartment is in a slice of real life of Buenos Aires and is not touristy at all, yet has easy access to the Subte and buses. Without a doubt, I will stay here again next time I am in Buenos Aires.
+easy and flexible check in time
+comfortable bed. Slept really well here!
+private sink and toilet
+massive apartment. Like huge. Full of great people who made my stay welcoming and easy (thank you Flor!)
+washing machine
+amazing wifi - there is actually two wifi networks here for the front and back parts of the place, so you will always get a good signal
+2 blocks from Venezuela subte and close to lots of buses that go to and from Recoleta, Palermo, etc
