This is a very good apartment, in an ideal location. The building is right on the river bank, close to Ponte Vecchio, with shops nearby. A very quick walk to/from the Uffizi, and not far to walk to the other main tourist sights. The area south of the river is well worth investigating too - very much where the Florentines live, with some great shops and trendy cafés and bars.
The apartment is spacious enough for three guests, four at a push (the double bed in the spare room is a small one). Ample hot water for showering, and with a dishwasher and washing machine to make life easier. There is a terrace at the back, but the weather was too wet and cool for us to use it; certainly useful in warmer weather for drying clothes, I’m sure. The kitchen has everything needed to make meals.
I imagine in the warmer months, mosquitoes could be a problem (we had a couple come in, and I got bitten twice), but there are net screens at the windows to help keep them out.
That aside, I highly recommend a stay in Tommaso’s place.
