I stayed here 3 times in 2 weeks. Porthouse is like Japan. Clean, quiet, convenient, independent and efficient. I liked the code system to get into the building and the room. The location is excellent. Its a 2 minute walk to the train station to get to Shinjuku (3 mins on the train) and there is a bus stop out the front directly to Shibuya. The room is clean, with a comfortable bed and a good shower. The other guests were quite and I hardly bumped ino anyone which usited me. I met the owner briefly and the owner's daughter in law. Both were lovely. This is a good place to stay.
