I stayed here about 3 weeks. Overall, great experience. Place is a bit small, but very well designed to function greatly. Best thing is the balcony, it is bigger than apartment itself! I was staying there during winter, but on sunny days I was able to enjoy it, it was magnificient.
My check in was smooth, Marco was always very friendly and fast to respond. Apartment's location is in a great place, very close to Trastevere station and nice restaurants, shopping places.
