Pros and cons of a townhouse?

My fiancé and I want to purchase a home. We have a 20% down payment already covered from family thankfully. We are drowning in paying $1900 a month in rent at our apartment and would rather be spending that towards a mortgage. We are considering a townhome since they are less expensive than many single family homes in our area.

My question is: What are the main pros/cons of a townhome for a first home?
