We had such a lovely stay in Florence. Our host was lovely from the off, giving good advice in regards to transport before hand and gave lots of local tips when we arrived.
The apartment itself was large and very clean and had everything you needed in there if you wanted to cook. The balcony is a good size which is great being so central. The apartment is roughly a 20 minute walk from the centre and had a few good restaurants on the same street.
Would highly recommend this apartment not only based on the hospitable host but on the location and the apartment itself.
