I reserved Teresa's apartment for friends and they all agreed it was even better than what you expected from the photos, as it was really spacious, very clean, well-equipped and welcoming.
Right in the heart of Florence, very close to San Lorenzo's Basilica and the Duomo, and just breaths away from the train station, it turned out to be a good choice for walks around the centre. Street noises would do no harm at all in the kitchen if the windows had a double blazing, but the overall experience was great, Teresa was amazing and the quality/price ratio was perfect. Recommended!
