Hi. My family and I will be staying at an Airbnb with address at 6 Chome-1 Kitakoiwa, Edogawa-ku, Tokyo-to. We already figured with the help of Google maps that we should take the airport limousine bus from Haneda to Senjuhashieki and then we can take the train at Senjuohashi Station to Keisei Koiwa station and then a 5 minute walk will get us to the Airbnb apartment.
My question is: would it cost terribly much if we took a taxi from Senjuhashieki to our Airbnb address?
Also, we are to meet very early with our tour guide at Hamamatsucho Bus Terminal the following day. Would it be better if we just took a taxi instead of the train? I understand that taxi fares are expensive in Japan but since there are 4 of us, I thought it might actually be more economical and convenient to take a cab.
Would appreciate hearing your suggestions. Thank you in advance.
