Andrea was lovely and a perfect host - he was in touch beforehand to make arrangements for our arrival from Venice and he met us at the station and took us to the apartment. He was also immediately contactable during our visit if we needed anything, and arranged a cab to take us to the airport on the day we left.
The apartment is perfect - quiet, secure, spotlessly clean and really close to everything. The kitchen was beautifully equipped and Andrea had provided the basics (olive oil, balsamic vinegar, salt and pepper) as well as some lovely Tuscan bread. There were also plenty of cleaning products and some insect spray. The sofa-bed is easily large enough for two people and very comfortable, so the place accommodates 4 very well. Bed linen and towels were clean and fresh and there is plenty of hot water and a washing machine - there were even a few basic toiletries in the bathroom.
The location is perfect - a quiet residential street within easy walking distance of everything - an extremely good supermarket about 7 minutes walk (Conad - not only is the food and wine excellent but it also has an amazing array of toiletries!), Santa Croce and the Duomo 5 mins, Ponte Vecchio about 15 mins (if you don't get distracted en route - which you probably will!). I'd been to Florence before so knew of its beautiful treasures, but Andrea had a couple of suggestions for things to visit which we took and were so glad we did - so if it's your first time in the city, take his advice! We will definitely be returning to Florence, and wouldn't consider staying anywhere else.
