Most importantly, the stay was fine. Nothing terrible happened and it's a decent hotel. That said, it was a bit of a disappointing stay.
Check in was fine, but I just sort of got handed my keys. There was a wedding going on, so maybe people were spread thin, and if so, I get it. But no one told me about the various restaurants or the fitness center or anything really... And there's no info in the room other than a QR code. No one gave me a wifi code so I went to call the front desk and there's no phone in the room. Little stuff makes a big difference when you've been traveling and land in a random spot at 9pm.
The room itself was ok. I know and like that The Line has an early 20th century vibe. But the walls in my room were all banged up and dirty from furniture being moved around and it just felt kind of grungy. And the shower... A trickle from the shower head, it reminded me of a shower I once took in a remote part of Jamaica from a barrel on the roof with a hose coming down.
The room itself was spacious and great and with lots of potential.
In comparison, my stays at Line LA have been incredible enough that I sought out The Line in DC on purpose. There was nothing terrible about this one that would like ruin your night's sleep or make you want to leave, I just came in excited to stay at The Line and left with a meh feeling.
