I found Interlet to be a shameless operation.
Interlet charge an expensive upfront fee for service that is much, much worse than any free agency. They tell barefaced lies about available properties in order to get you to pay the fee - it then turns out the properties are not available or way, way out of the budget range you specified. Interlet staff are really good at seeming friendly and reasonable before they\'ve got your money and when it\'s no hassle to them, but the second you don\'t go along with it all they turn around and become aggressive and deceitful, and try to force you to pay way above your budget for worse rooms than you were promised.
Stay the hell away!
