We had a very nice stay at Catia and Gigi's appartement. They gave us a very warm welcome, italian way. As Catia is a guide she'll give you all the advices you need. The appartement is very near the Vatican (10 min walk), 2 min walk from San Pietro railway station and a bus can take you to the center of Roma but it is anyway doable by foot (that's what we did). The appartement is beautiful and clean, as shown on the pictures. Thank you very much Catia and Gigi, all the best!
