havent stayed there but know where it is. bit out of the way but looks ok.try liberatos village or san lorenzothere both up other end of lassi. more expensive but white rocks is lovelly with its own beach.
p.s. weve been to kefalonia 4 times with kosmar,i dont think you'll beat them for prices and reps who know what there talking about.
my stepdaughter stayed there last summer(we were in the liberatos village).they are clean and tidy apartments and we were there in july and only 3 or 4 were being used.there is a bigger complex right next door and you can use their large pool and bar.only 5 mins walk from makries yialos beach.fairly steep uphill walk from main road(200 yds or so).pictures in the kosmar brochure,ok!
stayed here in 2000,anyone who knows lassi its 100 yards up hill opposite dolphin supermarket.can't recall a pool that close,but you can use any pool anyway. nice old couple own it.clean and tidy.
