Florence's place is central and very close to Eiffel tower and surrounded by many restaurants. I was lucky to stay for the Bastille Day, the concert and fireworks were just minutes away. Florence and his husband were very welcoming and trying their best to accommodate my schedules, which I could only confirm till the very last minute.
The building itself is a heritage building, with materials from Eiffel towel - I really like it, but it definitely has its age.
Overall, it's highly recommended for solo travelers who wants to stay in a central location with limited budget, but may not be too ideal for couples or families.
