I can recommend two possibilities which you may like to consider both with excellent reviews, recommended by Tom Brosnahan's
Turkey Travel Planner and within easy reach of Ephesus.
First of all in the centre of Selçuk
Hotel KalehanAnother option, a quiet oasis in the heart of Kuşadası, is
Villa Konak Hotel.
As the website reminds you, if you make your reservation directly with either hotel and mention that you are a Turkey Travel Planner user, you will be entitled to a 10% discount on the room rates.
Hope this is useful. If I can help further, do please let me know.
