If you really want to stay in Asakusa, this is a good place to go. The host is very responsive.
Positives - Lots of amenities, kitchen equipment, supplied toiletries, easy to check in
Negatives - A bit of a walk to the nearest train station. I underestimated how long the distance was. The bathrooms are generally not clean and are noticeably smelly. I may be being picky but all other bathrooms I've come across are perfectly clean with no smell, so this was off putting for me. Finally, the walls are VERY thin so expect to hear every tiny noise around you
Overall a good place to stay for a shorter stay but you may want to consider if you have the budget if you want to stay somewhere for an extended stay. You definitely are getting a good bargain by staying here and if you can put up with a little bit of annoyances than this is the place for you :)
