Strengths:
- location: very close to Uffizi, Ponte Vecchio, historical centre
- spacious apartment
- fully functional kitchen with basic things for cooking: oil, salt, pepper
- coffeemaker (moka) AND coffee
- AC works (but see below point)
- kind and responsive host
- device against mosquitos in the flat
- washing machine
Weaknesses:
- noise from the street early morning (05:30) because of street vendors pulling their carts through the nearby streets
- can get very hot during summer, opening the windows not really an option because of above mentioned point
- AC can get very loud as well
Verdict: In the summer expect it to be warm and/or bring earplugs, otherwise you can expect a nice stay :)
