Location, location, location.
A nice studio apartment on the fourth floor (steep stairs!) of a house in the middle of the old city center, just five minutes from the Spanish steps and around the corner of Via del Corso, with shops, bars and restaurants.
Inside it gets a bit warm and noisy in summer when the windows are open, but there is air conditioning. We also got a lovely welcome and introduction by Karyna (a colleague).
During our stay, we experienced a problem with the old door locks, which we luckily could solve ourselves...
