I stayed here for 2 months for work:
Good:
Central location, close to supermarkets, shops, restaurants, public transport
The apartment is pretty much equipped with everything you need for cooking and laundry (except no spices/cleaning products)
The agency responds surprisingly fast (within 24h) and they are very polite and helpful
Bad:
There's very little natural light in the apartment
I had a lot of trouble sleeping - because of the location it is very noisy and difficult to sleep at night, the garbage truck passes around 23h-23h30 and makes a ton of noise and there are usually screaming drunk people walking around outside
Depending on who is renting the other AirBnBs in the building, it might be very noisy inside too - I had to deal weeks with drunk people partying on Wed nights, barking dogs, and just in general people yelling, screaming or singing as they walked up the stairs in the middle of the night
Also, since it's so close to the square, you can hear all the music from the square. Which means hearing all the street performers sing/play the same songs over and over and over...
And the pigeons... they like to mate on the windowsill and there's nothing there to stop them from accessing the window sill so around 6 or 7 every morning they smash against the window!
Sometimes the shower just smells like sewage for no reason
