I'm sorry that you were not satisfied about your stay.
Only a few clarifications for other guest who will read your review.
1) according to (Hidden by Airbnb) maps (anyone could check it personally) from "La casina" to "piazza san Marco" it takes 16 minutes walking.
2)I work also on sunday and often my father comes to bring guests keys; I always advised guests that my father cannot speak english and i'll give them all the information needed,guests also have my phone number and they can call me or text me for any issue anytime.
3. I bought personally the second pair of sheets ,we gave you, the day before your arrival because we had a problem wiht the washing machine (the previous guest can confirm it),that's because shets seems hard...they were just new!
3)I'm sorry for neighbours noises,you should have called me.
4)If you needed more toilet paper you should have just to asked for.
Anyway i take account of your review and i'll try to improve other stays.ù
Greetings from Florence
