Our stay at the Arlington Hotel was... inconsistent. Before staying here, we wondered why some reviewers glowed about the hotel, while others were extremely disappointed. We can now see why folks wrote both types of reviews.
The positives - the hotel seems nicely designed, with large, quiet rooms (we didn't hear any sounds from the room next door, even though we could hear them when in the hallway). The heated pool and the outdoor hot tub, plus the kids playroom in the basement were nice amenities that our kids really enjoyed. And, the location worked well-enough as a home base for trips to Bretton Woods for skiing.
Needs improvement - general upkeep. Upon arrival, we noted some bits of stool in the toilet bowl, and requested a re-cleaning. The housekeeping staff seemed somewhat overwhelmed that night, and the person who came to clean the toilet bowl also wiped it down with a soiled rag, and then proceeded to wipe the toilet seat with the same rag. Based on our observations of different hairs on the bathroom sink, we couldn't be sure if the sink had been similarly wiped.
Also, the ceiling had clear watermarks and stains where there must have been a leak. The pillows were very thick and firm (not a positive) such that our heads were pushed up at an uncomfortable angle. And, we weren't sure if the sheets on one of the beds had been changed, as we found human hairs of various colors on the sheets. During our stay, the hotel fire alarm system was also set off, and resulted in a lobby covered in water. We never found out what happened, as there was no follow-up announcement or information provided. Finally, prior guests seemed to have poor respect for the hotel, as almost all signs in the hotel had at least a few letters scratched off (take a guess what someone would scratch off from 'Pool').
Overall, we would avoid returning to this hotel.
