If you are visiting Ancient Ephesus and get a chance to tour the Terrace Houses, do so. They are well worth a visit, as they are extremely well preserved, and give a good idea how the wealthier citizens lived.

The houses are located inside Ancient Ephesus, but there is a separate admission charge of 10 Turkish lira. They take about 20 minutes to see. It's best if you have a knowledgeable guide, since there isn't a lot of signage. The houses are preserved under a high-tech ceiling, which can get a little warm; and there are stairs to climb. But the houses are fascinating.

There are many frescoes and mosaic floors in excellent shape (including a rather naughty fresco!). You can see how the ancient citizens lived, cooked, ate, slept, and carried out their other daily activities. Very enlightening!
