The location of the appartment is excellent. It is really at two steps from the Colosseum.
Other comments say it is a noisy place but we didn't hear anything from inside and we sleep very well indeed.
Also, there is the good attentions from Andrea and Cristiana. They prepared a crib for our 2 years old baby and everyday ask us if we were enjoying. Last day Andrea arranged a cupboard for our luggage wich was very convenient.
On arrival, Cristiana told us a lot of information about Rome and the neighbourhood. There are plenty of restaurants and a 24 h open supermarket on the block. Thanks of their indications, we were able to find the nearest pharmacy when we needed it.
We had the perfect Roman holidays!
