We've only got nice things to say !
Marta wasn't there when we were in Florence but Yeh did a really good job on his own !
We arrived late (9 p.m.) and still he took time to give us good places for food and activities in Florence.
He also cooked for us one night and it was a really nice evening :)
The room is clean, we had our fan and a mosquito repellent.
And one of the best part is the great location of the appartment (50 meters from the ponte Vecchio and then everything at walking distance).
We strongly recommand Marta and Yeh as hosts if you're looking for good company and location.
See you in France ;)
