Gumaro's place is amazing. Yes there is a large road nearby making the lower balcony a little noisy, but if you can get over that, it's possibly the best airbnb I've ever stayed in. That said, I had NO PROBLEM with noise once that balcony window was closed. Upstairs is particularly peaceful and the views of the neighborhood are breathtaking.
The house is thoughtfully designed - down to the shower window that opens to the rooftop garden and views of the neighborhood. Or the floodlights that illuminate the gorgeous tree outside the window at night.
Definitely don't hesitate if this is the area of the city you want to explore. It's cozy, bright, and absolutely delightful.
