We met with Melanie's sister who was delightful and extremely helpful. The apartment is brilliantly located near the Spanish Steps with all the things you need in a reasonably compact space. The detailed guide to what to see nearby and how to run the apartment - including the washing machine - was much appreciated and Melanie was always only a text away if needed. Note that there are stairs to access the apartment. In summary, a great location in the heart of Rome with very helpful hosts.
