Thanks to Ivan, we had a great (even better than great) stay in Buenos Aires.
The place is lovely and there is enough space for 4 people.
I particularly thank Ivan for the cleanliness of the place, the clean sheets on the beds, the towels for each person (lovely attention) and the useful kitchen supplies : a perfect host!
Everything was perfect! :)
I just recommend people straying at Ivan's to bring earplugs, the streets of Buenos Aires can be sometimes noisy.
