The stay with Katerina was really great. The room looks like on the pictures (even better in reality), was very clean and comfortable and there is a lot of space. Communication with Katerina was without a problem and we have no problem finding the place. It´s located ten minutes from the center (train station Santa Maria Novella).
Katerina is very friendly and made me and my boyfriend feel welcome. She let us also use the washing mashine and made us breakfast the two mornings she was there with us. She has an amazing dog Jackie, which we absolutely loved, he is really adorable.
I would recommend the stay at Katerina to everyone and we would definitely stay with her again.
