Marie's Oasis is perfectly situated in the historical heart of Florence. It's just off the well-connected via dei Neri, but on a quieter street. It's close to most of the main attractions, but quite a walk from the railway station so it's highly recommended to take a taxi to/from there.
The Oasis is clean and very spacious, and we love Marie's decorating style. We didn't use the well-appointed kitchen much, except for breakfast. But we loved having the washing machine to catch up on laundry. There are no window screens, so beware of the mosquitoes! My husband and I both got bitten alive! The cooling fans were a lifesaver since we had to keep the windows closed all the time.
Marie was very welcoming and helpful throughout our stay. We had difficulty accessing the wi-fi network, and Marie came promptly to address the issue. (The wi-fi base just needed to be reset.) She also provided some great restaurant and fresh market suggestions.
We highly recommend Marie's Oasis. We would book it again if we are ever fortunate enough to return to Florence.
