Wonderful place to stay! The location was great for reaching everything we wanted in the city. The apartment is roomy and has an air conditioner right by the bed.
The check in/out process is super easy. I was able to reserve my place here last second, on the train to Florence. We were in the "grey apartment."
The only way this place could be better is with the shower. There's no curtain/wall on the side so it sprays on the ground near the toilet unless you have it adjusted in one specific way... which is hard to use. The hot water heater is also very small, so if you're taking seperate showers one of you is likely to get a cold one.
Also, the pillows are a bit uncomfortable- but that's just the nature of traveling.
