My son and I had a great stay at Ascanio's place. I can highly recommend it. The apartment is centrally located closed by the station and it is fully functional even with a few coffee capsules. Check in was very easy and friendly. The place was spotlessly clean. There is a list in the place with all the sights and recommendations for restaurants. We have tried a few of them and they were all great. So, this is a great place for your next trip to Rome.
PS: As you might read in some reviews, there is sometimes a smell in the bathroom/toilet. I has more to do with old Roman houses and the piping systems rather cleanliness. (-: As said the place is well kept, nicely furnitured, fully functional and clean.
