We had a wonderful time staying at Shakira's apartment. It was the perfect location for us close to transport and minutes to the Piazza Di Duomo and easy walk to the Uffitzi. It's a well set up apartment with everything you could ask for. We were able to stay in one night and cook a meal as well as be down the street from plenty of eateries. The photos describe the facilities well. The place was clean and tidy and very comfortable. The bed was a bit firmer than I'm used to but we still slept through ok. Other reviews mention noise at night but it wasn't that bad unless you're a very light sleeper. You are I the middle of a busy city so it's to be expected.
My communication with Shakira was excellent, she is very prompt and informative. We only met Shakira's sister but she was friendly and explained how the apartment worked.
I'd certainly stay at this location again.
