Don't get me wrong this is a nice hotel and everything but there was a power shortage last night due to outside problem. It is not the power shortage that's the problem but my room was on the sixth floor when that happens and I went outside my room to try to find the fire escape stairs. Not a single emergence exit sign was visible. I was in total darkness. Other guest found the same on different floors. I don't know about you but in my country they will not allow the hotel to operate under this condition. There is not one single emergency or fire exit sign at this hotel. Take note this is a fire trap that one would hear about when traveling overseas. Hence my overall rating not to be confused with the quality that the staff and rooms are at the moment.

I stayed at the LK Renaissance for three nights.

Pros:
Good location
Comfortable bed
Free wi-fi in the room (one of the reasons I chose it over Tim Boutique Hotel)
Nice pool area, albeit pool is small
Studio room was quiet and had a nice view of big trees in vacant lot

Cons:
Front desk people were indifferent and not friendly - check-out was especially bad.
Linens were old and tired
Breakfast was mediocre (for the price of room)
Bathroom was in bad condition - no shower curtain, mold in corners, water pressure
Low end bathroom amenities (soaps, etc.)
Furniture was a little tired

I probably would not stay here again unless the price was a lot lower.

Given your choices in Pattaya, this is not a really bad place. It's well located, the lobby and the pool are quite nice and the rooms are decent. The staff is generally friendly. And surprise, the minibar isn't outrageously expensive. You could definitely find a worse value for your baht.

But this is why the LK can't be anything other than average in my book: The place, by virture of its location, is always noisy. You've got to bring your earplugs if you turn in before 2am, period. I know it's Pattaya, but you can find a quieter hotel of similar value. The rooms are in need of maintenance (paint, grouting, upholstery, etc.). The breakfast is an 'order off the menu' place of spectacularly mediocre possibilities. Finally, I extended my stay a day, but the front desk wouldn't hear of giving me my pre-booked rate on the additional day, and charged me the full walk-in rate--which is the fastest way I can think of for a hotel to prevent me from recommending them. Give another three or four star hotel in the area a chance before trying this one.

This hotel is centrally located in Pattaya city. It is clean and comfortable. We really enjoyed our stay there. The hotel staff are friendly.
I recommend you to ask for a quiet room not near the street if you don't want to sleep with the music of go-go bars nearby in the night.
Highly recommended.
