I really loved Jo's place. As other reviews mentioned, it gets loud at night. I personally think that it adds to the charm. The noise coming from outside is usually groups of people singing in unison, or just laughing together.
The apartment itself is very cozy but location is the real draw of this place. You are within walking distance of everything you could need and in a particularly beautiful part of the city. Jo is very kind and helpful, too. I really recommend this place!
