For me everything was perfect about Shinjuku Sharehouse: The directions were accurate, I had no problems finding it and Min waited for me to check in. My room was spacious, everything is clean, the common area is great and the rooftop is just awesome. The location itself is very convenient. There are shops and restaurants super close by and it's a 5-10 minutes walk to Kabukicho and Shinjuku Station.
Travelling alone for the first time, I surely came to the right guesthouse. Min was a great host and I met a lot of other great people from around the world. I had the best time at Min & Haru's place! I will definitely come back!!
