Fantastic apartment and host. It's a well equipped, stylish, comfortable flat in a great location a little bit away from the centre, but everything is really easy to get to by walking or by the metro. The metro also goes all the way out to Pompeii and Salerno, which is handy as well.
Anna was really quick to sort any problems we had as well as being flexible about our arrival time and an extra friend staying for one night.
Would highly recommend
