Just finished my two week quarantine at Silom Serene Hotel
Pros: contrary to reviews, the internet speed is ~10mb/second. Not great, but usable. After one week of quarantine they let you go out for an hour everyday. The pool area is decent. They do have a custom menu called Arnos which serve American food
Downsides: the food was nut low, but you do get to select your choice of meal everyday. You end up paying $1400 for the whole two weeks for a shitty room and shitty food. Also, the staff calls you 6 times a day. Literally. Temperature twice a day, and then asking about food three times a day. It's annoying
If you end up going to a hotel that doesnt have usable internet (which seems common), you can buy pocket wifi off lazada (this will require a thai phone number, however)
If you're landing in the next two months, PM me and I can help drop off pocket wifi/alcohol/books or whatever I can help out with. you will NOT have a chance to grab pocket wifi at the thai airport as they bus you straight from the airport to your hotel
Here are some pics of stay:
