Lu's place is just short walking distance from Kuramae station. The rooms are clean and spacious, compared to other hotels I stayed at my past visits to Tokyo. There's a supermarket that open 24/7 just few mins away, also some interesting shops, cafe and restaurants in the area. However, few things to note.
One is that the bathroom curtain is too short, causing difficulty when dressing after shower. People outside may see you naked and the towels provided are too small to cover the whole body (maybe this's cultural problem though).
Secondly, the apartment has no elevator, so it was exhausted to carry big luggages up and down to/from the fourth floor.
Overall we had a great stay at Lu's. Great choice if you travel with group of friends.
