Agustina's apartment is just great. It's close to everything yet very quiet, everyone in the building is very nice and it's squeaky clean. Also, the big wardrobe is great, since you actually have space for your stuff.
Besides that, Agustina is VERY, VERY nice. She'd check up on me every week (I was there for almost 2 months), but wasn't invasive at all.
I can't think of anything that's not nice to say about her or her place. Besides that, I forgot my glasses there and she's arranged for me to get them back.
Very recommended. Also, in summer, the pool is SUPER nice. :)
