What a delightful little apartment! It had everything you could need - a comfy bed, excellent kitchen and a shower room, but best of all was the veranda/terrace area with table, chairs and comfy seats and a view out over the rooftops of Rome. The carillon from the bell tower was an added bonus!
Luis' assistant, Emiliano met us and dealt with check out and was extremely helpful giving us basic information about supermarkets, eating places and getting about Rome.
It is situated a few 100m from the Termini so is ideally located for transport links, but we walked most places. It is in easy walking distance of the Colosseum, Trevi Fountain (dry at the moment, sadly) and the Spanish Steps. There are all sorts of shops nearby too.
Highly recommended!
