Rothamsted Scientist for 3 month furnished

Hey there, am looking for a short term (3 months, December-February) stay in the Harpenden area, while I work with my company in Rothamsted research. I'm the R&D lead for a startup so will be working usually between 9-6ish, Monday - Friday, with some hours possible outside of that. I will be relying on public transport to and from work with some walking absolutely fine. I'd ideally like a double room for my girlfriend to occasionally visit, I expect maybe one weekend a month. I will frequently be travelling home so shouldn't be in the house much on weekends, just through the week. No real deal breakers apart from good Wifi access and a desk foe my computer, so I can chill in my downtime. I tend to meal prep lots of food in advance so some decent fridge space would be great too. Thanks!
