🌿 IMPT Hotels
Oniro City, athens

Sustainable & green accommodation: IMPT lists eco-friendly hotels, green-certified stays, sustainable guesthouses, and responsible travel options — from carbon-neutral hotels and eco lodges to environmentally friendly B&Bs and net-zero accommodation. Every booking removes 1 tonne of verified CO₂ at the lowest price guarantee — same as Booking.com or better.

🌍 Your Carbon Impact at This Hotel

An average hotel night produces roughly 35 kg of CO₂ — from air conditioning, laundry, lighting, and food. When you book Oniro City through IMPT, we retire 1,000 kg of UN-verified carbon removal credits. That's not carbon-neutral. That's carbon-negative.

"The rooms were large for a European hotel, the shower was hot with generous water flow, and the balcony was great for relaxing and drying clothes. The breakfast yogurt was particularly delicious. The staff was courteous and efficient. They even had a room for us very early in the morning.\n\nThe elevator only fits 3 people and is very slow. But not a big deal...the stairs were also very convenient."

"We expected more. Although similarly priced, the room did not have the style or ambiance of Coco-mat Hotel located nearby. The noise travelled up the stairwell, the room was sterile, and the bed was saggy.\n\nOn the positive side, the room was clean, we appreciated the quality toiletries and found the location perfect for walking to main attractions.\n\nThe breakfast service was excellent, but under staffed and it would have been easier to enjoy if the server was better supported.\n\nThe front desk team were responsive but lacked the charm and hospitality we have come to expect in Greece."

"Absolutely a most terrific little boutique hotel in Kolonaki (and conveniently close to Lykavittos proper). The staff are above & beyond helpful! The rooms are lovely, with a modern decor, and great showers (including water pressure). Breakfast is included, and it is a great one at that, w/ plenty of options. Great value for a reasonable price point. Cannot say enough good things about Oniro City in Kolonaki!!"
