"Very clean room and public spaces. But, if you want your room cleaned (bed, bath, garbage) you have to tell them otherwise that only happens every 3rd day."

10/10 Excellent
"Stayed here on a last minute trip to Disney and the location is great! So close to the park, less than a 10 minute walk. Right in front of the hotel are good places and a market, which was great because our daughter still wants milk before bed, so we were able to grab that on the way back from the park. Room size was good, we did a two bed room and that worked for us, the space between the wall and the 2nd bed near the bathroom was a bit close, but it was fine. We were a corner room right near the staircase and we never heard anyone coming up or noise from anyone. The pool looked nice but we didn’t get a chance to use it because the day we were going to use it, it was very windy and cold compared to previous days. We would 100% stay here again"

10/10 Excellent
"They deserve a great review, it’s a hidden gem for sure. Loved the size of the room, how everything actually worked including the bathroom and shower. Saw maintenance crews there every day making sure everything was working. They cleaned the room really well (there’s a barcode to leave a tip, please do this. I did for the one time we requested them). There were extra towels, a nice view and location. There is a lot of traffic noise but that isn’t a big deal for everything else you get. Parking is tight but we didn’t realize there was underground parking until after. The breakfast was well maintained, it rotated every other day. The potatoes were so good! I wish the country gravy were available the days that had them. The staff kept everything clean during breakfast, but when it says closes at 10 that means get out, not just stop serving. Most importantly I felt safe there with my family. I hope the prices stay like they were for the next time I’ll be looking to this place first."
