My sister and I had a wonderful week in Florence, partly because Guido's apartment is perfectly located for walking and sightseeing. It's really close to everything, so we could go out for a short time or for many hours, and it was always easy to pop back home for a rest or to drop off new purchases. We knew there were about 50 steps up to the apartment, and it didn't present a problem for us (two fairly fit women, both around 70.) The street below is busy so there is noise, but we expected that in a central location, and it didn't present a problem. The twin beds were just to our liking and the kitchen, bath, and living room are nicely appointed. There's a pleasant restaurant located right downstairs called Gusto Leo--super friendly staff.
Guido is a great communicator and everything went smoothly with arrival and getting the keys. Guido was friendly and gracious when we met, explaining all we needed to know about the apartment clearly and completely but also providing a detailed written guide. He had thoughtfully provided bread, milk, and butter and cookies for us, and there was coffee as well--really nice after a long and tiring trip to have some food on hand already. The wifi was great, worked perfectly, and one day Guido took the time to send us a detailed text about a special restaurant he had just discovered, with instructions how to get there. On our last day, I got a bit nervous about getting a taxi and texted him, and he responded immediately and helpfully. We use AirBnB a lot, and an efficient, reliable and friendly host offering a stellar location for walking everywhere make Guido's place outstanding in our experience.
