This is a good sized apartment suitable for up to 6 guests - two double bedrooms and two single bedrooms. There is very little indoor sitting space but the terrace is very nice - large and with good views so one can do almost everything here as long as you don't get bad weather. You should be aware that it is an apartment with other apartments above and to one side, this didn't cause any problem for us. You do hear a bit from the neighbors but this was not a problem. One great asset is that there is parking outside the door.
We walked into town all the time but it does take 15 minutes or so and is up / down quite a few steps. This was not a problem for us and we included two over 70's. This is a big advantage as driving around Cephalu and parking are not easy.
We did not meet the host as she had covid but she was quick to reply and very helpful. We had a great holiday and would recommend this apartment.
