We found it to be a good size for a couple traveling, and great location - close to restaurants and cafes, not far from a metro, and walking distance to Palermo Vieje and the MALBA. We loved the neighborhood.
We only used the kitchen for breakfast and the fridge for leftovers, and it had what we needed.
There wasn't enough hot water for two consecutive (American) showers - but if you're one person, or one showers in the morning and one at night, it should be fine.
We thought it was good value for what we paid.
