I had an absolutely amazing time staying at Abbeyglen! I actually extended my stay for a second night after I arrived because I couldn't bear to leave yet.
The afternoon tea is a wonderful experience (warm, cozy, delicious...), and the champagne reception was a great way of meeting other guests and learning more about the area. Breakfast is absolutely lovely, and is included with the room. Dinner is offered in the hotel as well -- the food was heavenly, and the price was on par with restaurants in the town of Clifden.
The room is just as described, and it definitely feels luxurious. The bathroom is even more wonderful than it looks in these photos! The room is tucked in beside the elevator, and while I didn't hear much noise from the elevator, I could hear people talking in the corridor outside as they passed my room. The building's water heater system is below the window, so there is some very faint white noise from that as well.
I didn't receive a response to a last-minute message I sent through AirBNB, but since this is a real hotel that happens to post some rooms on AirBNB, I would recommend just calling/emailing them directly if you have any questions. Upon arrival, the staff was all supremely friendly and helpful, and the owner is gracious and kind.
I'm already planning my next trip back to Ireland, and I'll definitely stay here again when I return!
