We mainly chose this hotel due to its proximity to Santa Maria Novella station - the rest of Florence is within walking distance anyway. It's on the third floor of a building, there are separate hotels on other floors so check the brass plaques before you go up. There is an awesome retro lift with the self-service closing doors that is like the one in the Matrix. If you're in a group or wheelchair it would be several trips.
Room is clean and tidy, spacious enough. We where offered a choice of two rooms and went with upstairs, I think it was previously an attic but had a skylight and good ventilation. There is a TV in the room with a range of satellite channels although it's tiny. Plenty of unpacking space and a good wardrobe for hanging up clothes. Separate bathroom was very clean and had plenty of amenities. Rooms are labelled 'private' (no numbers) so not sure how you'd find it drunk or something. You would need to check when/if reception closes as you need to be buzzed in to get through the security door.
I think it's a husband and wife team running it and they are quite friendly, very helpful with pointing out laundromats, restaurants etc. in the local area. They have wifi and a computer you can use but otherwise no services on site. For entertainment there is a roof terrace but it's pretty lame and the view is obstructed (see photo).
Breakfast was pretty basic: cereal, yoghurt, some pastries, juice, tea and coffee. All bundled in for 90 euro per night, I wouldn't pay separately for the breakfast. Not sure what that buys you in the area in early May.

if you want a nice clean and inexpensive place to stay in florence this is it, within walking distance to everything, the breakfast is good enough to start the day, right near the train station, staff friendly, bathroom spacious and clean, couldnt ask for more

My wife and I have just visited Florence and we have to say the hotel we stayed in although 2 star gave a 4 star service. The Angelica hotel is superbly placed to visit all the main tourist venues and is just a 3 minute walk from the railway station. The hotel is family run and they could not have been more helpful. The room we had was of an adequate size and very clean with a really nice en suite bathroom.

The breakfast was of the continental style with proper english tea available. The hotel occupies the third floor of the building and is quite small. There is the inevitable noise you expect in cities with traffic and revellers but this did not affect our stay too much.

A very good experience and we will definetly stay at this hotel again.

Great location, near the train station, restaurants and tourist attractions. Good Price for what it offers. Staff willing to provide information. Good breakfast. Comfortable and clean room. I recommend the stay.
The heater didn't work very well at night. They could provide the wi-fi signal inside the room. The curfew about midnight can be a problem for your plans.
