This house is awesome! It is in a great place, very close to Asakusa, very good communication with all the places in Tokyo by underground, and close enough to go to the station with heavy luggage. Besides, even if Asakusa is very close so you have shops, restaurants and everything close for night life, the place itself is in a residential and quiet home. If that is not enough, it is sound proof so you can sleep as a log.
It is a very big appartment, which is really good because most places in Tokyo are small rooms where you don't even have a place to eat. Here you have several rooms (we didn't even use one of them, which is a pity because it is beautiful, looks like a ship cabin) and a big table and it is great even for 8 people. We were just 3 so you can imagine how comfortable it was for us.
Tadarts is a very nice host and he left some breakfast for us when we arrived. He's not very talkative in person but he does all the best to help.
The only downside of this is having to climb two levels of stairs to reach the appartment, but you only have to carry luggage twice so I think it is a very small downside if you're going to stay several days as we did.
I really recommend this place if you're going to stay several days in Tokyo to explore and enjoy completely the city!
