The Roma was simply impeccable, brand new when we were there earlier this year. If you are planning to drive to it, forget it. Park your car and roll your luggage to it. The street is very narrow and it will take you hours to 'plug' into it. Then you will block the traffic and....
Very close to it there is a pretty cool drinking place with a few tapas (a hundred feet away?) it look like a little run down grocery store but it has excellent stuff.
Hope you have a great time,
