Advice on housing as a student

Hello guys I'll be moving to tokyo soon( 26th of this month) as a student. Unfortunately I didn't get a uni dorm so I started looking for private housing. One of my seniors who's working in the same lab that I will be going to gave me contact information of an agent who said he will let me know what all options are available for me soon but nothing yet. So i started looking online and one of my acquaintances told me about gghouse, I found a decent looking place in meguro (my university is located in meguro, Tokyo ) but Idk how gghouse and their service is, and I also just wanted to ask your opinion on my situation. Thanks in advance:)
