The staying experience was horrible AND WANT MY MONEY BACK !!! I stayed here ( k guesthouse number 1 premium gangnam ) for 5 nights, EVERY NIGHTS the bar opposite to the hotel played VERY NOISY MUSIC, even it is 2am !!!!!! It is THE WORST hotel experience I've ever had. I phoned to the lobby for help , the guy told me he phoned to the bar to lower the sound , but it was absolutely NO USE at all. What's more , the bar even played the music Louder !!!! That's very rude . And this hotel is very near the road , so at midnight 3am you can hear the sound of motorcycles and cars . i couldnt sleep good every nights. I won't recommend this hotel to anybody, to be frank , unless you can sleep with loud sound disco music . Last but not least , there is no toilet paper , teeth brush and toothpaste provided , you need to ask the lobby staff for toilet paper , i feel it is strange . Even The hotel name's include "premium " in it , it is nothing related to "premium " .. And they dont have room cleaning service , unless you stay more than 3 nights, they can provide room cleaning service once every 3 days. And yes they dont have elevator.
