It is also possible to fly to New York and take a bus to Pittsburgh. This might be a bit cheaper, depending where you are travelling from.
If you are interested in this option and want to compare prices, the recommended bus company is megabus.com | Low cost bus tickets.
This is our friends' beautiful airbnb. It is right by a river and very close to the location. If you are interested, please let us know. We will book it privately and not through airbnb to avoid fees. It fits about 10 people.
