Welcome to Android Central! Agree with above, and I'd even say it's an entry-level phone, rather than a mid-level. Downsides to consider about the Desire 300:
1. No 4G
2. Only 512 MB system RAM, which is very low these days. It means fewer apps can remain open in memory, which means slower app opening and switching.
3. 4 GB of storage ROM means probably about 1 GB (or even less) available to you, since a good portion of that will be taken up by the OS and Blinkfeed (and other bloatware). This means not much room for you to install apps. You can't install apps onto a microSD card.
4. Very low resolution of 800x480.
You can probably do much better, but as mentioned above, it depends on your budget and the availability where you are. Is the Moto G available there? That's the best value out there right now.
