I would ask that wait staff pay careful attention when alerted to a food sensitivity.

9.4/10 Exceptional! (280 reviews)
We chose Inn by the Sea because it was advertised as a “pet-friendly” property with beach access for pets, which was a key factor in our decision. Unfortunately, our experience didn’t quite align with those expectations.
We arrived on a Sunday around noon and, as expected, our room wasn’t ready (check-in is at 4:00pm). However, unlike many hotels, we were not offered anything while we waited — no welcome drink, light refreshment, or even an early check-in estimate — despite having to wait the full four hours.
Once we checked in, we were told our assigned room was not pet-friendly, and we would be charged for any accidents — despite booking under the premise that this was a pet-friendly stay. Additionally, the restaurant only allows pets in the outdoor seating area, and the pool area is not pet-friendly at all. So while the hotel does accommodate pets in some areas, it’s misleading to call it fully pet-friendly when the main guest amenities are off-limits.
That said, the property is beautiful and most of the staff were friendly and professional, which we appreciated. But overall, if you’re traveling with a pet and hoping for a truly integrated experience, this may not be the best fit.

This is probably the cleanest, most beautiful hotel for the money we’ve ever stayed in. The nightly rate was comparable to the other hotel rooms in town, but here you get a huge spacious apartment! All new, chic, and very comfortable. Easy to walk to Wharf St. and the dining and shopping area too! The manager was very responsive, friendly and accommodating as well! This place is a gem!
