I lived there for a while (in the Solemar Hotel) so know Ixia very well.
The hotel is basic and a bit dated looking but clean, friendly and very central. It's set back a little bit from the busy coast road but there's still some traffic noise so if that bothers you i'd put in a request for a quiet room.
Ixia was one of the first resorts on the island so it's a bit shabby and tired looking in parts but there's great facilities - lots of restaurants/bars to choose from. The beach is sand and shingle and very breezy so most people tend to stick poolside for sunbathing. You'll find the resort is on the breezier side of the island but in August this is very much a POSITIVE! Another plus is the close proximity to Rhodes Town, there's a good regular bus service or you can flag down a taxi on the main road. Great for exploring town and a good money saver for excursions as you can buy your boat trips directly in Mandraki Harbour.
Hope this helps, anymore feel free to ask
