We enjoyed our stay at Mayu's very much.
You just need to know that this is a loud place. At the two crossing streets below the apartment are a couple of places where the nightlife goes on and the street is very loud until about 2am especially at weekends. And the A/C is old but works but makes a lot of noise as well.
Mayu was extremely helpful and super friendly. She helped us with everything and was very responsive.
