Если обязательно нужно в Коктебель - то лучше в "Приморье". If you definitely need to go to Koktebel, then it is better to go to Primorye.

Against the general background of dirty (due to the rarely located trash cans and the low level of culture of vacationers) the streets of Koktebel, Primorye stands out for its cleanliness and well-groomedness. Pros: good rooms in building 1, there is not only an adult, but also a children's pool, a good playground, a quality buffet with a traditional Russian menu, for an additional (low by Moscow standards) billiards and a tennis court. Friendly staff. Even the maids, waiters and cleaners are of Slavic appearance (as we understood, students in practice). There is some attempt to limit the passage of non-seaside tourists to the beach, so even at 10 am after breakfast there is where to settle down on the pebble beach. 24-hour first-aid post (insurance or payment required, but we were given treatment for free). Of the minuses (small, but noticeable after Europe): at a high price of living, a paid safe, the duties of the maids do not include making the bed, instead of coffee in the dining room, a very dubious drink, you can’t go into the pool with your umbrella - rent it.
But in general, it is worth going to Koktebel to look at the beautiful nature, walk along the hills and swim in the cool sea. The village itself is nothing of interest. the private sector is just awful - even if you rent a house in a good house, you will have to walk along a dirty (sometimes smelly) street in a crowd of tourists to the beach. We did not regret that we did not save money and chose Primorye. Another thing is that for a good rest it is better to go to Europe after all.
