We had a great stay in this apartment: it is larger than the pictures look, and perfectly located for seeing the sights of Florence -- right by the Ponte Vecchio. The wifi held up for video calls (though was stronger in the bedroom than elsewhere), and it was great to have a full kitchen (stovetop/microwave/fridge/coffee) and washing machine. The water pressure was weak but not as bad as we feared from previous reviews. Ermiola was helpful in showing us how the apartment worked and advice on sights in Florence.
We were visiting during a heat wave, and were very grateful for the A/C. The kitchen does not have an A/C or fan, so it gets quite hot if it is warm outside. It would have been nice to have some seating in the bedroom beyond the bed, as it was hot to work at the table in the kitchen. One of the shades was not working in the bedroom.
One note for check-in: when we arrived we had a bit of a miscommunication, as the person meeting us was waiting upstairs for us to message and not waiting for us outside as they had told us they would be. Thankfully we had cell data to message, but it may be helpful to get the name of the buzzer or triple check that they will be meeting you outside.
