The apartament can only be described as cosy and very old-timey. It has a very nice ambiance - overall a perfect place to come back to and rest after a full and tiring day of sight-seeing. The location is also great, the distance between major landmarks is what really sells it (10 minute walk from the Vatican, 6 minute walk to the Pantheon, 5 minutes to the Spanish Steps, etc.). All of the utilities provided worked well and the bed is comfortable! I really enjoyed my stay at Via dei Prefetti and I'm hoping to come back soon. Rafaela, the key keeper, was professional, friendly and very helpful.
PS You may be surprised if you need to use the fridge ;)
