True Bangkok Luxury - 5 star all the way

10.0

First time staying at this property and what a wow experience. It is a true 5 star luxury hotel with Bangkok’s best hospitality staff. Location wise - very convenient location, BTS (Skytrain) stop just a 2 minute walk away. Easy walk up to Chitlom / Erawan etc. Rooms are beautifully appointed. All amenities including Smart TVs. Bathrooms spot on. Service is outstanding across all departments. Nothing is a problem. Genuinely friendly. Loved the pool area - a true oasis in the heart of Bangkok. I used it every day - even just for a quick dip. Pool attendants amazing. The onsite Japanese restaurant is fabulous, so good I took clients there 2 days in a row. Overall this was a 10/10 stay for me on so many levels. Would love to return again soon. This is 5 star luxury at its very best.
