We loved our stay at Michele's Microloft. The apartment was in a great location, in a quiet and interesting neighbourhood; only a ten/fifteen minute walk from the city centre, and very close to the San Spirito piazza which is a vibrant space with lots of great bars and restaurants. There are also some great boutique shops in the area, excellent gelato and a market on Sundays etc.
Michele is a lovely host, and was happy to help if we needed anything. The apartment is small, but very comfortable, with aircon and cooking equipment. We had no issues with the shower being in the toilet either, as some reviews had mentioned.
Can highly recommend this place for an excellent stay in beautiful Florence!
