My wife and I stayed at Casa Winkler for 3 nights during our short trip to Rome. What a fantastic little gem! In a great location, the apartment served us well. For a studio apartment it's perfect with high ceilings and all the facilities you would need. Luigi is a fantastic host and allowed us to check in early. The location is a short walk to many of Rome's historic sites so it's perfect for walking around.
Loved our stay and would highly recommend it for couples or single travellers.
