Hotel recommendations in Delhi for two days sight seeing trip

[amind]

hi,

Looking for hotel recommendations on which area/hotel to stay that would
be convenient for visiting major sight seeing attractions in Delhi. Since I am
not familiar with Delhi, online searching has not helped me decide on which
part of Delhi to book.

Hotel budget for family of four : Upto Rs 3500-5000 per day

Planning to travel in the HoHo tourist bus, explore Delhi Metro and ease of
airport transfer. Agra part of the trip has already been finalized.

Thanks in advance.
