Which are the nearest budget places to stay near the Homewood campus of JHU? is there any B&B,Hotel,Motel, Homestay nearby which is in a walking distance?
There is a hotel next to campus but not budget. Otherwise, you are staying downtown or in Towson area. Without a car, downtown is best option. Everywhere will between mile and 1.5 miles to campus.
How is the public transport access from Ramada Limited Baltimore West hotel to the Homewood Campus of JHU? Whats the access of this hotel from the bus stop of long distance buses to New York .What is the distance between the his hotel and Homewood Campus of JHU?
You don't want to stay there. Pick a hotel downtown. There are holiday inns, sleep inns, which are budget and convenient.
The Doubletree Colonnade adjacent to campus is a bit fancy, but it will only be slightly more expensive than staying at a hotel downtown. The Ramada Limited West Bmore is going to be budget and maybe run down. Public transit from there to JHU Homewood would be a huge hassle. I would advise against that.
If price is a big of a factor, try for a room at the Baltimore International Hostel/Hostelling International-Baltimore and take a bus - I think #3 - up Charles St to get to the Homewood campus.
