My stay here was wonderful! The location is perfect: you're just around the corner from a COTO and a Día (two supermarkets), a Havanna (great coffee/alfajores), and on the same street as Farola de Villa Crespo (delicious empanadas), and a Venezuelan bakery. You're super close to a bus stop which will take you just about anywhere you want to go for real cheap.
The apartment is great. It took me a couple minutes to learn how to use some of the appliances and how to lock/unlock the front door but after that learning curve everything worked great.
This is an excellent location to stay when you're in Buenos Aires. It's safe, quiet, yet close to action and only 10 minutes away from Palermo by bus. I highly recommend staying here!
