The short-term rental market is showing signs of fatigue this summer in two of the “strong cards” of Greek tourism, Mykonos and Santorini, as a decline in prices is observed, despite the increase in demand in Mykonos, while in Santorini the repercussions of the seismic activity of February continue to be felt in terms of overnight stays.
At the same time, Kos is recording a spectacular increase in demand, with short-term rentals following a dynamic course and prices stabilizing.
This is shown by the latest short-term rental data that AirDNA draws from platforms such as Airbnb, and Tornos News has obtained exclusively, regarding how the demand for short-term rentals is evolving so far in July and August 2025 in Mykonos, Santorini, and Kos.
Decrease in demand and prices in Santorini
In particular, the effects of the geological phenomena in Santorini are also recorded in the demand for short-term rentals, which in July 2025 is reduced by 3% compared to the corresponding month of 2024. However, August shows a recovery with demand reaching +6.1% compared to the same month last year.
In terms of the number of nights for which demand is recorded, Santorini is experiencing losses compared to 2024 levels in both July and August, with nights down by 3,366 (this year’s total of 62,935) and 1,062 (for a total of 53,164) respectively.
Prices are also falling, likely in an attempt by owners to make up for lost bookings. Specifically, in July 2025, the average daily rate (ADR) is 365.32 euros compared to 388.69 euros last year, and in August it is 360.11 euros compared to 365.42 euros in the corresponding month of 2024.
However, the supply of short-term rental properties moved upwards compared to 2024, with an average of 4,282 available listings per day recorded in July, an increase of 295 compared to July 2024, and 4,300 in August, an increase of 364 compared to last August.
Mykonos: Double-digit increase in demand – 780 euros is the average price in July
In terms of demand, Mykonos shows an increase of 12.5% ??in July and 19.6% in August. Although all short-term rental indicators are up, the average daily rate (ADR) is showing “correction” trends, resulting in July at 780 euros compared to 811.48 euros last year and in August at 708.49 euros compared to 784.96 euros in the same month of 2024.
The number of nights for which there was demand for July is 51,101, compared to 45,557 last year, and in August, at 41,253, compared to 35,685 last year.
The number of available listings on the island has also increased this summer, which on average, per day, in July is 3,247 compared to 3,136 last year, and in August, at 3,251, compared to 2,995 last year.
Impressive growth in Kos
In Kos, on the other hand, the growth of short-term rentals is impressive. Demand for July shows an increase of 16.8% compared to July 2024 and for August +27.5%.
The number of nights for which there was demand for July amounts to 16,526, almost 2,400 more than in July 2024, while in August their number is 14,508 compared to 11,597 in the corresponding month last year.
The available listings per day, on average, for July amount to 910 compared to 730 last year, and for August, to 909 compared to 704 last year.

Athens is a strong attraction for American visitors
