Alejandro's place was just as described - bright and sunny, comfortable, and had everything I needed for a long(ish) stay in the heart of Buenos Aires! The location is very convenient to get around. Note that it is on a very busy street, so there's noise from the street and busses. I brought earplugs and had no problem.
The water pressure in the shower is amazing, the kitchen had everything I needed, and the blinds worked well to block out the light at night. I would recommend to friends and stay again!
