We stayed 3 nights at Stefano's My Suite Rome 2, which is perfectly located literally just around the corner from the Pantheon. Stefano was very responsive to our inquiries pre-arrival and organized an airport pick-up which appreciated a lot after the long flight.
Stefano and Valeria welcomed us at the property, explained the property and gave us valuable hints about the neighborhood (e.g. Where to get the best coffee). Both were very friendly and helpful.
The smartly renovated apartment itself is on the third floor (no elevator). It has a separate little kitchen, a living/dining area, 2 bathrooms and a bedroom. The rooms are not huge, but for a couple more than enough space to spend a few days (or weeks). The apartment has effective and working air-conditioning and even a small washing machine. There are no spectacular views from the apartment itself as the windows lead to a courtyard, but the place is quiet despite being very centrally located.
We enjoyed our stay a lot and definitely recommend this place.
