The Good: The unit was perfectly fine for what we were looking for.
The Bad: Our check in and communication experience was abysmal. We booked this place on short notice, and even accounting for that, the performance was poor.
We booked 30 or so minutes before the stated check-in time. Shortly thereafter, we got an email from GLS customer service requesting our credit card information, which is in direct contradiction of AirBnB policy as we understand it. We confirmed with AirBnB that we shouldn't forward that information and did not. But we're already off to an inauspicious beginning.
When we arrived we couldn't get in the building. (During a tropical storm that was working its way over the East Coast, no less...) So, we stood in the pouring rain and called the phone number provided with the AirBnB confirmation for check-in assistance. No one answered. It did have voicemail, but it immediately hung up without letting us leave a message. We tried at least three times to confirm it wasn't us. It wasn't us. We waited in the rain until someone who happened to be leaving let us into the building.
Now we're inside. Dripping wet, but no longer in the rain. Small victory, but we’ll take it. At that point, while we had an AirBnB confirmation, the concierge had not received a confirmation from GLS, and couldn’t give us the keys. The concierge was a very nice woman who was apologetic about the situation, but was unable to let us into the unit without confirmation from GLS. No worries, short notice booking, understandable. We’ll get in touch with GLS. GLS was nowhere to be found. They have a 24/7 help line. No one answered the phone. We called several times and were connected with an answering service at one point. We left a message. Never heard back. Ok, GLS has an emergency help line. (If you're think no one answered that call either, trust your instincts...) We tried contacting AirBnB to figure out what the issue was, but they were really only able to try to contact the host, who (wait for it) didn't seem to be answering their calls either… After about an hour of sitting in the lobby, dripping wet, the concierge finally received a booking confirmation from GLS and gave us the keys. Well, key, singular. We were staying for several days and wanted to have another set so we could each have one as we had separate things to do. That worked out as well as you'd expect given what you've already read. (The sheets were kind of scratchy too, but that seems rather minor in the grand scheme of things…)
So. Yes. Nice place. Good location. I would hazard a guess that if you book this with more notice, you may have a better experience than we did. Maybe. Hopefully.
