Guido's apartment is just perfect and I can not recommend it enough. Right in the heart of the city (2 minute stroll to the Uffizi gallery and the river). It is so accessible to everything the city has to offer. All the sights are walking distance, plus the street itself where the apartment is located is quiet (during the day) and pretty. We fell in love with Florence during our stay and wanted to live there.
We traveled by train to get there and the station is a handy 15 minute walk from the apartment, which is also good if you wish to do day trips out during your trip, e.g Pisa etc.
The apartment has a large double room with a separate living area including lounge, dinning table, kitchen and separate bathroom. The apartment is very clean and well stocked for guests. There is a maintenance guy who lives in the bottom of the tower who looks after everything and is helpful. Plus good wifi and a handy map were provided too. We spent most evenings cooking in as the apartment felt so comfortable and homely.
Our only slight negative during the stay was that it can get a little noisy at night, but this is to be expected with its central location within the city. We stayed in August anyway so the noise of the air conditioning unit (very much appreciated during this hot month) drowned out most other noises.
Guido is a lovely host. Although we never met him, communication was great and he was always on hand to answer any questions or help us during our stay. He even messaged to check how we were enjoying our stay. I would highly recommend staying here and look forward to future visits.
