"Stunning! View romantic, cozy and just so magical!"

10.0

Truly the most magical experience that I have ever had in Key West. I was there on my honeymoon visiting. The staff went above and beyond to make our stay absolutely amazing. The place is beautiful and it's so relaxing. Sitting in the pool and being able to look out over the ocean was just incredible!

"Highly recommended"

10.0

This place was awesome! The accommodations were very comfortable and clean. We initially booked 5 nights, but had to move out for the last 2 due to someone buying out the entire house for a birthday party. The management was very helpful getting us relocated, even though it was a hassle. The only issue was that on the evening before we left, we found that the maid had left us with dirty coffee cups and glasses. She also failed to fill up our soap in the shower. No biggie, just want management to know it. It was actually such a non issue we forgot to tell the manager ourself. Highly recommend this place!

"Best Place to Honeymoon"

10.0

This was our honeymoon destination! We picked the perfect place! Upon our arrival, our room was ready early and they had a bottle of champagne waiting on us in our room! We took advantage of all they had to offer. The pool was perfect and the bar and restaurant on the property were excellent! All the staff is friendly and helpful. We will definitely be back!

The Southernmost House, was beautiful, and the staff was wonderful. The complimentary breakfast was very good and had many options to choose from. They always had cold bottles of water for all who stayed there, and the outside porches were just wonderful to relax on at all times of the day

"A terrific stay, even though it wasn’t what we planned."

10.0

We had booked a trip to Key West for our anniversary and were supposed to stay in one of the oceanfront bungalows. Upon our arrival they informed us that our room was not available due to a roof leak so the entire ceiling had been torn out and the space was unusable. We were very disappointed as we were really looking forward to spending time chilling out overlooking the ocean. They offered us the use of the one bedroom apartment in the Lopez house. We expected to be pretty bummed out by it since it did not have an ocean view but it ended up being an absolutely wonderful space and we had a terrific time. We sat on one of the side porches and got in some great people watching instead of the ocean. There were some renovations happening elsewhere in the building so we had the place almost all to ourselves. The apartment was very nicely appointed with a full kitchen ( even an icemaker!), large rooms and comfortable high quality furnishings. The addition of a coffee table would help. The manager Alex and the staff really bent over backward to help us so we really appreciated all their efforts. They even gave us a nice break on the price for our inconvenience so we’re happy campers.
