We stayed in the Urban Lokoo Loft for three nights. Roberta was a great host. She collected us from the airport and brought us to the loft so we could drop our bags off as we were too early for check in. She then brought us to a local restaurant where we got lunch. The loft was exactly as shown in the pictures. Extremely modern and with all amenities you could require during your stay, including a complimentary bottle of wine and some food for breakfast.
In terms of location it is about a 10 minute walk to the Colosseum and a 2 minute walk to the metro.
We loved the open plan layout of the studio the fact that you could plug your phone into the surround sound system.
I would highly recommend this accommodation to anyone coming to stay in Rome.
