We have just returned from a week staying in this lovely apartment and we all had a great time. There is plenty of space for everyone to spread out and it is perfectly located within very easy walking distance of many historical sites and literally hundreds of bars and restaurants.
The only negatives are the tiny kitchen (it is very well equipped but impractical if you want to make anything other than salads etc) and there was also quite a lot of street noise.
I would definitely return and recommend to other travellers.
