    Long weekend at the house

    Spent a long weekend at the house. Great atmosphere and lots of history. Great location and the view is awesome. The staff is good and for the most part is supportive. The room shows its age as the dehumidifier runs non stop and I had to empty it once a day. The paint is peeling and the windows rattle when there is a strong wind. The bed was super comfortable and the AC cools the room nicely. We had trouble with the drain on the bath tub which was never corrected - I used a rag to keep the water in the tub. The noise from the bar and the food truck is distracting when laying around the pool as the fence is right up to people sitting and eating. The price is a little high for such a run down place. Several leaks visible on the ceilings, railing on stairs missing parts, etc. but it has history and is quite old. Comparing it to the neighboring properties, I would probably go back next door on my next trip.

    Perfect stay at Southernmost House

    My girlfriend & I just got back home from a stay at Southernmost House, 3/19-22/26. We went to Key West for my bday, and our experience couldn’t have been better. We stayed in rm 108 across the brick street from the main house, a large room with living room, dining area, full kitchen ( my gf has special dietary restrictions so we cook) , large bedroom & bath. Beautiful & so comfortable. Wraparound porch with its own private courtyard. At one point we had a shower malfunction so right away we were given use of rm 109 while our shower was being promptly repaired. Every need was catered to. Big thank you’s to all the Southernmost House staff, and most particularly to the very kind gentleman at the main desk who checked us in & checked with us periodically to see if we needed anything. He was a gem. Embarrassed I can’t recall his name, but he seemed to always be there ! We both give our highest recommendation for SmH, and hope to return ASAP

    Paul and Nancy's vacation

    This was our third stay at this property and as always we were well satisfied. This is a great site with a great deal of historical significance. Everyone from Presidents to World leaders and some not so great people such as Mafia types have stayed here in the past. It has to be very difficult to keep a property like this in great shape as well as provide great service but they do. We did notice that there were some "attention to detail issues" such as painting and caulking that needs updating but that's an ongoing thing that we hope they stay ahead of in order to keep this a must stop while visiting Key West.

    Beautiful hotel but beds need upgrade

    The mansion house was beautiful very well kept with tons of historic features and artwork inside. The pool was also very nice. Free bottled water was included throughout the stay. We really enjoyed sitting at the seaside Café and tequila bar. The pizza was amazing. Breakfast included in the stay was a nice perk (pastries, bagels, fruits, yogurt, coffee and tea). Parking is an additional fee of $25/night. They have about 6 spots available. Staff was friendly. A major downside of this hotel is at the beds. Need to be upgraded. They are extremely hard and after four nights it was difficult to function with so little sleep. I I travel frequently and very rarely have such trouble sleeping due to the mattress. At the price point and the overall concept of the hotel, I would expect the beds to be a bit nicer. Even a pillow topper wouldhelp if they aren’t ready to replace the mattresses. There’s also construction going on on the south Street side, which is disclose on the website, however it is worth mentioning if anyone is staying in the next few months. The construction starts early in the morning as is expected, but there is no sleeping in at this hotel. The reason I rated this with three stars is solely due to the comfort of the bed and noise levels from construction. Considering this price point and the fact the only reason I need the room is to sleep I feel that this is a pretty big deal that they need to resolve. I booked a hotel on the quieter side of Duvall where everything closes down at 6 or 7 PM so we could get a solid night sleep during our trip but unfortunately, that did not happen.
