Need weekly Mansion near Haneda Area

I am visiting Tokyo next week and will stay there for 90 days (company project work), My office will be somewhere near Haneda.
Can anyone give any idea about weekly mansions in Haneda or nearby Haneda Area?

Yes. There're some weekly mansions near Kamata station (about 15 min to Haneda) but you need Japanese to book it.

How much far the Kamata to Haneda, and also is there any direct train available for that ?

You can check train times and costs on:

As I posted before, it takes about 15 min from Kamata to Haneda and there's a direct train service (Keikyu line).

As the area is more residential district than business district, reasonable accomodations can be found in this area. There's a shopping street and many eating places near the station.

Thanks for that info,
I am an Indian and also strict (pure) vegetarian. Can you guys tell about any Indian/pure vegetarian restaurant in that Kamata area?
