I stayed at Maria's for four nights when I extended my stay in Buenos Aires. Maria is very nice and has a beautiful home. It's architecturally interesting. The neighborhood is safe and well located for transportation. The rooms have nice balconies and are inviting.
If you're built like me, 215lbs, 6ft. the bed in the rose/pink room is a tight fit, a small twin. Just a heads up. There's no cooking in the kitchen, and only one key for the building door. No locks on rooms or the apartment door. I don't mind that, but maybe some folk would. But everything felt safe and secure in my opinion. There is a nice rooftop garden with a table and chairs, too.
Plenty of hip bars, trendy cafes, boutique shops, parks, people walking within several blocks. The area was too hipster for my blood, but if you like that sort of thing, you'll love Palermo. I prefer a more working class area, but that's just me.
And close to several milongas (Canning, La Viruta, Cheek to Cheek... club Malcolm, but that one is a dud).
I'd recommend the place. I'd stay there again.
Gracías, María!
Fue un ratito muy cómodo en la casa tuya. Hasta la vuelta! Suerte.
