Ok, so staying at PIT today to try out the Duo Studio. The room, for 2 people, is totally fine.
A couple of nice touches is that a little chair and ottoman are accessible even with the bed down. Helps my DH who goes to bed later than me. There's also the make up mirror and I can use the armrest of the couch on the right to put my glasses at night.
Everything else is fine BUT there is a major deal breaker for me and that's the lack of a kitchen sink. I use the sink in the studio kitchens a lot and the one in the "bath area" (outside the bathroom) is too small and shallow.
Not a huge deal but they did a BLT on the sink situation here and it seems so short-sighted. Not a fan of the Duo and will avoid it in the future if I can. We had one booked in January and I canceled it.
