Grand Inter Residence — A New Building With Spacious Rooms in Khok Kham Where Sinsakhon Estate Workers Book Long Stays
If you have business near Sinsakhon Industrial Estate or the Khok Kham side of Samut Sakhon and you're tired of dated rooms, Grand Inter Residence (officially the Grand Inter Hotel) is the name locals bring up most. It's a tall residence block that opened in 2018, set directly opposite the Sinsakhon estate. What guests come back for isn't the design — it's clean rooms in a genuinely new building, suites with their own kitchenette, free parking, and a Trip.com score of 8.8 from 449 reviews, the highest among similarly priced stays in the province.
Grand Inter Residence is a tall grey-and-white block trimmed in brown, with a fretwork panel down the centre of the facade and a covered drop-off at the entrance — it looks new and well-kept from the street. It opened in 2018 with 79 rooms ranging from the 28 sqm Deluxe Twin up to the 56 sqm Executive Suite. Every room has a private balcony, air conditioning, fridge, flat-screen TV, kettle and a work desk, while the suites and Family Rooms add a small kitchenette and a separate sitting area. Several guests note the rooms feel larger than expected for the price, and clearly newer than other stays in the same area.
What gives this place an edge in Khok Kham is that it takes both daily and monthly bookings. Workers at the Sinsakhon estate and people on longer projects tend to book by the month here. The building has an on-site restaurant that serves breakfast and offers room service during limited hours, a gym, an upper-floor terrace, laundry service, a lift and a 24-hour front desk. The ground-floor lobby is an open, white-tiled space with marble-top tables, blue banquet chairs and a row of copper pendant lights — it doubles as the breakfast area.
One regular sums it up plainly: spacious, clean rooms in a new building, decent breakfast, friendly staff and a price per night that's hard to beat — the kind of place you return to every time work brings you to Samut Sakhon.
The suites and Family Rooms come with their own small kitchenette, which is what long-stay guests like most. A fridge, a counter and space to heat a simple meal mean people staying for weeks don't have to eat out every meal. The twin rooms are simply furnished in warm browns, with gold-framed Thai-pattern art above the bed and clean white linens. The rooms aren't luxurious or heavily styled — it's a clean apartment look — but the newness of the building makes it feel more comfortable than older hotels at the same rate.
Understand the location before you book. The hotel sits on the Khok Kham side opposite the Sinsakhon estate, not in central Mahachai. Wat Khok Kham is about 0.4 km away and the San Phanthai Norasing shrine roughly 0.8 km, with a 7-Eleven and a few rice-and-curry shops within a short walk. But getting to CentralPlaza Mahachai or Mahachai railway station means a drive of around 20 minutes. Guests with their own car have it easy thanks to free, generous parking — without one, keep Grab or a motorbike taxi handy, as public transport in this zone is thin.
The overall score is 8.8/10 from 449 Trip.com reviews — a high mark, and the largest review count among the province's budget stays. Cleanliness and service both score 8.9, location 8.7. The trade-offs to accept: there is no swimming pool, and this is a residence focused on rooms rather than resort-style facilities. Some reviews call the breakfast plain and not very varied, and because the property sits near the estate and the coast, a few guests mention trucks passing or an occasional odour on some days — worth knowing in advance so it's no surprise.
On price, Deluxe rooms start around ฿750/night for daily stays, with suites and the monthly rate working out far cheaper for longer visits. Getting a new building, a spacious room with a balcony and free parking in an industrial-estate area at this rate is genuinely hard to find. You don't need to book months ahead as you would for a resort, but rooms fill quickly when the estate has events on, so check availability one to two weeks out if your dates are set.
The bottom line: Grand Inter Residence works best for drivers with business at the Sinsakhon estate or on the Khok Kham side who want a new, spacious, clean room at a low rate. Long-stay guests get the most out of it thanks to the kitchenette suites and monthly rates. It's not for travellers who want to wander central Mahachai on foot or who need a pool. But if the goal is a comfortable night, a new room, easy parking and being right next to work, this is the most cost-effective option in the area.
