Just returned from 3 nights at the Condotti Inn.
First off, to echo a previous review, the guest house is un-inspiring from the outside and once through the front door, a little less so. Once up the stairs and across the courtyard, all is well. The lovely ladies that work here are so friendly and helpful. We stayed in room 5 that was spacious and well appointed. Continental breakfast was served in your room at a time to suit, this was just right to get you going for the day.
The key to this place is its location! You are 5 mins from the Trevi Fountain and Pantheon, Just across the river from the Vatican and no more than 10 mins from the Spanish Steps. The Colosseum is 10 mins away on the number 87 bus, the stop being 2 mins away.
This is just a great place to stay if you want a base camp that is very comfortable and so close to all the main attractions. Would highly recommend this B&B.
