Stayed here for 4 nights in May. This is a great location and convenient to everything. I never met Marco but his assistant Clara was wonderful and very helpful. She made airport transfer arrangements for us when we arrived and left. All emails were answered promptly. The place itself is unique...climbing the stairs in the red room was an adventure. The apartment was clean and tidy, but a bit damp. This may have been the weather while we were there. Would definitely stay here again and would recommend it for those looking for an adventure in one of the most convenient locations in Rome. For those interested in gelato, there are two great places within a few minutes walk.
