Our exclusive lounge for business travellers.

For guests seeking a heightened level of comfort and personal exclusivity, the Kasara Executive Lounge at our Bangkok business hotel is an inviting, well-appointed space accessible only to guests staying in the hotel’s suite categories or Garden Terrace Rooms.

Often referred to as a hotel within a hotel, our exclusive Lounge offers exclusive amenities and gourmet culinary offerings including hors d'oeuvres and refreshments, with premium beverages available from 5.30 pm. With complimentary use of private meeting rooms, it is the ideal place to conduct business, while couples and families will appreciate the assistance of a dedicated concierge, on hand to make restaurant reservations or offer sightseeing-planning tips.

Located on the first-floor level and overlooking the lobby area, the Lounge offers convenient express check-in and check-out, as well as other privileges. Only registered guests are entitled to access the Kasara Executive Lounge. Guests may invite visitors, subject to availability, at a supplementary charge.
