Where to live/Commute to Reston

Hello, I'm looking for some advise. I (fingers crossed) will have the opportunity to get a transfer from London to the USA with my job. My US office is in Reston and I will be required to commute twice a week. I'm used to expensive cost of living having lived in London so I'm hoping DC won't be a huge shock plus hopefully the US salary will still leave me better off than in London. I'm 25 female, single and excited at the prospect of relocating and starting a fresh. I have visited DC earlier this year but looking for some advise on where to live. I would prefer DC because I'd like to make the most of doing the tourist activities, joining sports clubs/ making new friends but also have friends and family come to visit me and show them round. I don't expect to have a car initially (unless necessary) so therefore would need to use the grey line to commute. It's only twice a week so I don't mind something up to 1hour ish commute which (my office is very close to RTC station).

Where would you recommend I live? I was looking at Rosslyn/Court House area. I see a lot of recommendation for Dupont/Logan Circle but I don't know if the commute is too long.

For extra background, I'm not into clubbing scene but I like hiking, walking, coffee and would like to find a club or group of friends and be able to attend NBA games, go to talks and seminars etc.

Looking to spend no more than $2,300 USD all in for a 1BD. Also do any flats come furnished or is it typical to furnish yourself? Must have in unit washer and dryer, I like the amenities of gym, pool, co-working space etc but that's not a requirement and see that more in Noma which is the wrong side of the city for me.
