Parco dei Principi has a great location on the north side of Villa Borghese but it is not close to main sites. There are buses that you can take but that can be tiresome. Booked a junior suite which was large, clean, with a big bathroom, separate dressing area and had a beautiful view over the park to St. Peter's. Breakfast included was decent; staff overall was good - not too friendly - but efficient. Go over 3 blocks to the Via Rossini which has a lot of very good restaurants and not too touristy since this is a more residential area. I'd recommend this place to older couples; not so much for families.
