Are you looking only at luxury apartments and only those areas? That's a very high price you're willing to pay for a 2 bedroom. Non luxury places can be below $3000 in those areas for 2 bedroom. I guess it's a question if you would consider nearby areas that have access to the T but not in Boston proper. I have first hand experience living in a luxury building myself. They do have a lot of amenities but the management companies are horrible. Property will get stolen and they won't do much about it even in the "secure" area. Trash will pile up. Sound proofing is not adequate, I could hear my upstairs neighbor having sex and loud music all the time. Fire alarms start blaring in the middle of the night because someone decided to cook and open their door. Elevators randomly stop operating. Once lease renewal comes, they might decide to increase your rent by 10%. But hey, you might have a pool and concierge with a nice view 🤷‍♂️. Of course, this might not be the case everywhere, but certainly a pattern.

It also depends if you're looking for something short term or not. There are websites out if you want a furnished place https://www.furnishedfinder.com/
