Stayed at Ficus' for a week - it was really comfortable and cosy. The place is located quite a bit far away from the JR Akihabara Station but it is very peaceful. There were some construction nearby during the period we stayed but it usually starts around 9am to 10am, so it wasn't a big issue.
The room is big enough to unload two luggages, has a bath+shower and most importantly, a toilet bowl that comes with seat warmer.
You can find many convenience stores around the area, about 1 min walk from the place. Vending machines are everywhere as well, a few just right around the corner. If you are planning to wash your clothes during your trip, Ficus actually has a washing machine and spinner/dryer on the ground floor - it doesn't require money to operate but do put a 500yen coin into their piggy bank afterwards. I left a 1000 yen note after using the appliances twice.
Ficus was very responsive and quick when addressing our queries, so we did not have much to worry about.
