There are many many hotel options in Rome, catering to all manner of budgets and vacation types. However, DG Prestige Rooms is the only one that has Maria, and that alone is reason enough to book here. I cannot stress enough how incredible she is - she doesn't speak English and I barely speak any Italian, but within a few minutes of arriving at the hotel I felt like I had found the Italian aunt that I didn't realize I was missing from my life, and she was a huge part of what made our trip so enjoyable. She's constantly enthusiastic, helpful, considerate and kind, and is an absolute credit to the hotel, the city and Italians generally! She also makes a mean capuccino, will ply you with pastries and will happily sit on hold for a half hour to get you a taxi - my daughter remarked that she would trust Maria with her life, and I totally agree with that.
DG, even without Maria, was great. Location was perfect, easily walkable to anything you want to do in the city, very clean and quiet. There is a fantastic restaurant, Vladimiro's, literally right around the corner, the breakfast is great and the rooms are very comfortable. The amount of keys required to access the property (street door, stair door, main door, room door) is perhaps a little intimidating to begin with, but we figured it out pretty quickly. Price is perfect - not too expensive, and in Rome you'll be out most of the day taking in all that this incredible city has to offer anyway, so save your money
