Honestly one of the best Airbnb experiences I've ever had. The place is so beautiful and awesome. Very spacious and well-appointed, full of beautiful design and so much character (high ceilings w/ interesting design, stained glass, the atrium room, etc.). It's a great mix of the original design elements from the library and modern updates. A huge kitchen, two bathrooms, and a washer/dryer are nice too! The photos on the listing are beautiful, but they still don't do it justice. You have to see it to believe it.
It was also really refreshing to rent from a local person who owned the property himself (rather than from a company). Gerardo met me at check-in and was so kind and warm. He went above and beyond to make me feel welcome and to ensure the place had nice touches throughout (like nice bath products from the natural body product shop that shares the building). He also offered some great local recommendations.
The location in Roma Norte is excellent as well, with so many delicious restaurants in walking distance, Plaza Rio de Janeiro around the corner, etc.
I had to conduct some video conferences while I was there, and the wifi worked really well.
I would stay there again in a heartbeat (and I hope to soon!).
