Hotel is old and poorly maintained, even worse, it looks it suffered from some kind of demolition in the past, for e.g.:
color from elevator doors drops off, elevators are not operational, many of lights in the passage are broken, doors toward the beach are suspended with parts of broken door steps, wardrobe in the room has some strange holes, beds are very uncomfortable, there are no recycle bins on the beach and so on. The beach is nothing special, at least if you take into account other nice places on Pelješac. FAR better choice by my opinion are beaches in Žuljana, Duba Pelješka and Trstenik, if you are with car and you are ready to make additional 20 to 30 km every day. The food is not very tasty, and the servings are insufficient, but frankly speaking, this is not the worst part of this hotel.
But there is something that should not happen in hotel where people from different European countries, mainly from Poland and Czech republic are coming to enjoy their holidays. Virtually every night some people of evidently low culture, usually drunk, (guests of hotel Komodor) were very loud in the front of room windows looking to the backyard between main hotel buildings.They didn't stop disturbing others sleeping in spite of warnings from some guests. And it was 2 o'clock in the morning! The hotel reception desk was not very far, but they didn't react as that wasn't their problem. On other occasions people from the reception desk were mostly pretty unfriendly and self occupied. They even didn't see some young guests rolled drunk on the floor in the front of hotel's entrance. Obviously there is no security stuff in this hotel to put some things in the order!
It seems hotel attracts some 'difficult' people. In the dinning room there is warning saying guests are not allowed to take away food (what 'normal' guests never do), but I accidentally saw a woman who put at least ten cans of pate and a lot of cheese and even bread in her bag and simply went out. Also, if You plan to take a romantic walk along the hotel's beach in the night, be prepared on the laser 'attack' from some (very) young children. And they sometimes direct the laser beam in your eyes, which is dangerous. I suppose their parents are not able to read the warning on body of green laser pointers stating that such behavior is health hazard (and as I know, free public use of green laser pointers is forbidden in Croatia).
And finally, the hotel maid came only once (!) in seven days, which is something I didn't experienced never before in hotels on Adriatic coast in Croatia. I was in dozens of them during last thirty years and Komodor was the worst example so far.
My advice is: don't spoil your holliday and stay away from Komodor!
