Siam Bangkok|2.01km from city centre
tayed at Twin Hotel recently and overall had a good experience. The hotel is very clean, and the location is excellent — super convenient for getting around. Staff were friendly and check-in was smooth. The design is a bit old-school, nothing bad, just slightly dated if you’re into modern aesthetics. My only real letdown was the view from my room. It was okay, but not my favorite — I personally love being on a high floor with a full city skyline view, and mine was facing another tower/building which felt kind of enclosed. Maybe just personal preference, but next time I’d request a room with a more open view. Would definitely stay again — just with a different room location next time!

Excellent hotel - great location out of the hustle and bustle of busy Bangkok but still close enough for a quick grab somewhere. Hotel provides a boat shuttle to Sathorn pier where you can take train or ferries up the river. Staff were so lovely and helpful. Two things were lost during our stay and both found quickly by staff, which we were very grateful. Breakfast was excellent - probably the best we’ve had! Very happy kids with fresh pancakes and waffles. Even an ice coffee station which we loved. There was some renovation work being completed while we were there but it wasn’t noticeable. Would definitely come back if staying in Bangkok again! Thank you everyone!

Location is good. Next to Erawan Shrine. Walking distance to Central World, Big C, and Platinum Mall. Need to climb and use the connecting overhead bridges, though. Hotel looks grand. We stayed in the suite, which is very big, with washer/dryer, microwave and stove. Mini-fridge is stocked with drinks and snacks which are free and replaced daily. Service is prompt and good.

Siam Bangkok|3.73km from city centre
I stayed here a few times. Friends wonder why i choose to stay on the outskirts of Bangkok. It is actually not far from the Bangkok city centre. Just 3 stops on the train, and i am in Siam Paragon. And the station is less than 10 min walk from the hotel. Being a little out of the city centre allows me to be away from the crowd when i have done what i needed to do in the city centre. Hotels in the city centre tend to have many people around and in the lobbying. Pullman Kingpower's surroundings are much quieter and serene. It is good to have a place to get away from the crowds and congestion of the city centre Also, this hotel is huge with its surroundings uncluttered or congested by high-rise buildings. Kingpower duty-free shopping mall next door offers free coach transfers to the airport twice a day. There is no need to buy anything to get on the coach. It also offers a free access lounge if you need it. Transfers and lounge are only for customers of the hotel and the mall. Around the hotel, there are many small traditional Thai style shops, trendy cafes and decent massage services. There is also a cinema in a shopping mall nearby that has also a supermarket, foodcourt and many wonderful restaurants and eateries.

Khaosan Road Bangkok|4.47km from city centre
Our go-to hotel when in Bangkok for a couple of nights. Yes, it's old and a bit worn, but the location suits us (close to the Grand Palace and Khao San Road) the pool is nice, they have a 24 hour desk, and provide safe luggage storage for a reasonable fee. Definitely not upscale or fancy, but we just came from a resort that cost 3x the price and the bed and sheets at the Royal were of much higher quality and comfort!

Lovely grand old hotel. It's the type of luxury and grandeur that you don't find anymore. The workers of the hotel are very accommodating and provide a great experience, always going out their way to help. There's two swimming pools - a bar pool in building A and a quieter full sized swimming pool in building D. The breakfast is varied, but if it's busy, sometimes popular things like salaami and eggs run out quickly. The breakfast is an early finish at 10am. There's also a fee restaurants on site. The hotel is walking distance to the Palace, temples and Khao San Road in one direction, and Siam in another. Would definitely stay here again.

All staff are greeting the guests nicely from the entrance to the front desk and escort us to the lounge checking in floor. The girls at the lounge checkin counters are even more professional and nice. We are staying at the 1BR Serenity suite which is spacious and classically designed. The bed and pillows are just perfect for everyone. The bathroom is huge and clean with bath tub (incl. bath foam, oil and salt). The day/ night beautiful scenery of the whole of Bangkok can be enjoyed from the top floor bar of the hotel. We must visit the hotel again next round to Bangkok.
