Very clean and well-maintained units with everything you need. The office is directly downstairs and operates 24 hours. The instruction book is exhaustive which answers many FAQs. There is also a free mini breakfast. Not in large portion but you can have a taste of everything. If that's not enough, the food price there is really affordable.
I was left at the airport in the morning and desperately needed a unit and I was happy to find Guner's place. They allowed me to check in early and the place is very clean and tidy.
