I know I should start with describing the flat, but sometimes a good service goes beyond that. Me and my husband were extremely delayed in checking in due to several unforeseen problems. Instead of arriving at 5pm we only arrived at 6:40pm and Claudio was there patiently waiting for us. And he received us with a smile which made us feel so welcome (and sorry for the delay). The flat is a small well decorated quaint flat in the centre! I mean really....the centre! Because it is so high up you don't hear the noise of the street but you can get anywhere within a 10min walk. It is close to restaurants, cafes, a small Carrefour market, to the shops, a nightclub...it is simply in the HEART of Florence. The house was clean, with towels, a small kitchen, a decent sized bathroom, an AC!! which saved us in the 38oC heat, an a nice comfy bed. All you need for a couple of days of exploring Florence. I would go again.
On a side note: This flat is for 2 people maximum...otherwise it is too small. It also has no lift, so beware if you have big heavy luggage. However one does not expect this from apartments in the centre.
