We had a lovely time staying in Ketty's apartment. It is very very central to all the sites and we were able to walk most places (although we did catch cabs back after long days out. The apartment had everything we needed although we did not cook there and the roof terrace was superb after a long day's walking. Just the place to relax with a glass of wine before setting out for dinner. There were 2 of us in the party and the flat was plenty big enough; however it would be very cosy if there were 4 of you. Would recommend the place highly.
