First off, it wasn't easy to find. We rode the shinkansen and got to tokyo late. It was raining and we had luggage so we decided to take a taxi from tokyo station because Nanami instructed that taxis can surely get us to the place so we did that instead of hopping on and off the trains. Unfortunately, the taxi driver couldn't find it the first time (we gave the full address, it wasn't on google maps, we even used the link on the instructions) and we found ourselves lost for a bit. We had to piece together clues from photos given in the instructions because the color of the building when the photo was taken and now is different so we or the driver couldn't recognize it especially at night. Thankfully, once we found it, it was easy to enter the building (except for carrying the luggage up the stairs because there was no elevator).
The nearest station going straight to Narita airport is quite a walk when you have luggage with you so I would recommend others to consider if they're fine lugging around their bags for 15-20 min to asakusa station.
Aside from that, though, the place itself was nice and really clean. It had the basic amenities and the washing machine was a real lifesaver. They put translations for all the remotes which was great! They also had dish soap and hand soap so we didn't need to buy anymore. I like how the ceiling fan wasn't just for decoration and could actually be used.
The place is 12-15 min away from sensoji temple and from the shipping streets. We discovered a lot of good food there!
I would still stay here if I only had light luggage with me.
