I stayed there with two children. Now for us Sevastopol = Sofia and nothing else.
The rooms are clean, the bed is changed as is customary in all hotels, nothing clogs or leaks, hot water is around the clock, the pool is clean enough to swim, as mentioned below. City noise is not heard at all, although a bus stop is a five-minute walk away.
Delicious breakfasts included in the room rate.
Any breakage of something in the room is eliminated within a minimum time.
Free meeting at the station of Sevastopol. For a very reasonable fee, they can also be met in Simferopol at the airport or train station.
From me marks "5" in all nominations.
Convenient - near Chersonesos (for me, it is the purpose of travel).
House in the private sector. Near the market.
Hot water, clean sheets, nice hosts.
