We had a wonderful stay at Valentina & Antonios apartment in the heart of Rome. They are really nice hosts, who supported us at the arrival and provided a lot of tipps for bars/restaurants nearby. The apartment itself was very clean, well-equiped and perfectly located at Campo de Fiori. You can reach all sightseeing spots from Vatican, Colosseum to Vila Borghese by food, so no need for public transport. We can totally recommend this place
