Have you found out if the utilities are included? Rent is one thing, but phone, gas, electricity, water and other bills keep coming in, especially power bills over winter. This might influence your decision.

Can you take over the lease, and sub-let the other room to someone? If things don't work out you can ask the other person to leave and choose to sub-let again or live alone. It puts you in charge of your living arrangements. If you choose to share, it might take a few attempts to find someone who fits your lifestyle, pays their share of the bills and is considerate towards your pets.

It's very challenging to find someone to share with, but when I tell stories about the guy who disappeared for a few days every rent day, so I had to cover his rent (I ended up moving out and he stayed even after I had all utilities disconnected), his mother warning me not to hassle him as he stopped taking his psych meds, the obsessive compulsive who'd arrange the chairs at exactly 90 degrees and sniff the teatowels for cleanliness every night, the one who would have a glass in one hand and a cask of red wine in the other by 8am, the one who installed a security alarm and barrier in his bedroom to keep my cat out etc, it makes for a laugh or two.

I hope it works out as it sounds like a fantastic place
