There's a restaurant on site. Public spaces have free WiFi and wired Internet. You'll find a business center on site. Days Inn by Wyndham Beijing Haidian also features a fitness center, express check-in, and express check-out. Free self parking is available.
The hotel is close to the metro, and we were allowed to check in at 8:00 AM instead of 2:00 PM, which was helpful after a long flight from Brussels, Belgium, to Beijing, China, allowing us to sleep after a six-hour jet lag.
The room and bathroom were plenty big enough, but there were too many mosquito bites.
There are fleas in the room; I got bitten on my arms and legs. The A/C was not working the night before we were leaving. Housekeeping did not provide sufficient amenities. Overall, I will not stay there again.
