We stayed at Mamo's Florence - Hibisco apartment during a 24 hour trip to Florence. The pros: (1) the location was very central, on a very warm and lively street, literally steps from the Duomo, (2) it was spacious and clean and (3) Mamo's communication / check in instructions were very clear. The cons: (1) the infrastructure of the building (like many in Florence) does not support the "luxuries" you would expect for the nightly rate - the A/C is weak at best and we did not have any hot water, (2) we woke up in the morning with a swarm of ants in our bags, which is odd because they didn't contain any unsealed food, (3) the pictures must have been taken a few years ago and / or photoshopped because the apartment has experienced a bit of wear and tear since they were taken. Overall, I'd recommend Mamo's apartment for the location alone, but you can probably get a better bang for your buck and will be more comfortable in a hotel.
