Most hotels in the Delhi area, unless 5 star, have a noise problem. The Park Lane is well situated in a residential area and away from traffic and car horns, crowds, construction, etc. The hotel is well managed, staff know their job and are friendly, rooms are good for the price, dining room is efficient and will cater to needs (less chilli, etc).
The wonderful Delhi Metro is a shortish ride on a 3 wheeler, and some good local shopping areas accessable by cycle rickshaw. Max Healthcare hospital is also nearby.
For those looking for Delhi tourist traps, they are too far away for this, although Kingdom of Dreams is nearby. As with most hotels, arranging taxis for you is exhorbitant, best if you find a local service which charges Govt rates. Airport is about half an hour away and therefor accessable.
