What issues should I expect when booking apartments/hotels in Batumi during peak season (August)?

A traveler advises booking Batumi accommodation during peak season through a tour agency rather than Booking.com, since agencies will always swap your room if problems arise, whereas Booking is considered unreliable for this. He also noted that in his area (farther from downtown, closer to the airport) the power never went out, and it's near a bus stop, a children's hospital, and bus route #16 to Carrefour.

At Sunshine Apartments in Alliance Batumi, a guest who booked a 42 m² studio was given a room of only about 25 m², with staff citing a 3-day-long AC repair; shower gel and shampoo bottles were empty, and the power went out several times.

Due to overbooking, the hotel was swapped a day before departure for a supposedly "upgraded" one that actually had dirty linens and mold in the bathroom; the power went out twice during the stay and the elevator to the 25th floor was broken.

Despite housing issues, travelers suggest not to stress and instead walk along the seaside boulevard toward the Ali and Nino statue (pine and cypress trees), swim in the sea, enjoy Georgian food and wine, and take day trips to Martvili waterfalls/Magnetic Sands and Prometheus Cave.

Locals point out that in Adjara the true peak season is only August, so having basics like a bed, pillow, and water can already be considered decent service — while prices are usually lower than at other Georgian resorts.
