First off, since the officetel is brand new, it was very neat and pleasant, which was great. The cleaning was excellent as well! We didn't even need to turn on the heating because the insulation was so good; we just opened the windows frequently for ventilation and managed just fine. Above all, the host was kind and responded promptly, which was nice. I'm not sure if it will always be like this, but registering our visitor parking via the wall pad was convenient, making it easy to park two cars.
There is a GS Supermarket right on the first floor, which was great for buying quick snacks. Also, there are many Korean buffets nearby (which were practically the best), so meal planning was very convenient and satisfying. Additionally, you can see inside the dome where Starfield is under construction, which was fun for us since we enjoy watching the building progress.
Now for the downsides. Since my family was staying, we thought the bed might be small, so we brought our own mattresses. However, the bed was very hard and felt more like springs than support, so we didn't use them at all. The office chair was also unusable because the wheels were too stiff and difficult to move. Also, I imagine some guests might not bring their own towels, but there isn't a single one provided, so you should definitely bring your own. There is conditioner, but no shampoo, so it would be best to bring your own! I think it would be great if these aspects could be improved in the long run.
Parking was a bit inconvenient in the evening as we had to go down to B4 or B5, but we were able to park on B1 or B2 during the day.
Overall, however, since we are the type to pack well, we were extremely satisfied, and it was a great choice for our stay! We were also grateful that they adjusted our check-in time to an early hour to accommodate our situation of visiting with a baby!
