Marco's place is very well situated and as described. (NB: We didn't use the kitchen) The apartment is in a short walking distant to the station and the main attractions. Marco's brother welcomed us on time. He was very friendly and spent some time answering our questions and giving us some tips regarding our stay in Florence. He had some great recommendation in restaurants. However, you need to be aware that the apartment is situated in a busy street with a beer bar next door. The bar has some tables outside right under the windows. We had to keep the windows closed at night because of the noise and the cigarette smell. However once the windows were closed, we weren't bothered anymore.
I will very much recommend Marco's place to friends.
