Fairly simple adventure, arrived late, unpacked, showered, hit the town for sunset, got in late, woke up early, had breakfast (little underwhelming for me), packed up and left! Lady at reception pointed out a free place to park a few blocks away which was appreciated :) Would definitely recommend.

This is an amazing place very well situated just off Duvall Street and close to the beaches, room was excellent and staff very friendly apart from the ladies at the bar who were rude and unwelcoming

Only issue was the air conditioning unit was very noisy so couldn't sleep with it on and then couldn't sleep because it was too hot!

Lovely quiet hotel
Lovely hotel in a quiet neighbourhood just off Duval St. Very welcoming, lovely room, great shower and lots of loungers and towels available by the two pools. Only slight negative was the breakfast, which was a bit limited to pastries, waffles, toast and cereals - some fresh fruit or yoghurts would hVe been appreciated!

We do NOT recommend & will NOT be staying again
Negatives: parking, bed comfort and questionable sheet cleanliness When we checked in for our 2 night stay, we were assigned parking space#2 (out of 7 total spaces). The second day, we came back from our excursion and our space was taken. The front desk said someone made a mistake and gave our space away, so they gave us space #7, which was on a different street further away from our room. The beds and pillows are extremely firm and uncomfortable (i woke up every 2 hours both nights) AND the sheets seemed clean but had a stain on them. We will not be staying there again.

Ok stay
It was okay, the room didn’t look like the pictures. Also, it sucked I had to pay for my own parking. Front desk was ok and didn’t really try to help about parking situation. Most of the hotels around have parking included. Wish the room looked like the pictures. Bathroom was a little dirty as well.

Nice hotel on the south end of town.
Southernmost Inn is charming, clean, and comfortable. Our room was clean, 2 shower heads in the big walk in shower. The bedding was super comfortable. The room was only cleaned upon request which we liked because it limited contact. The breakfast was only pre packaged items you had to ask for at the front desk, but there was a Starbucks coffee machine 24/7. Parking was $25 a day extra which was not explained anywhere, so he forwarded. There are only 6 spots available for the 15+ rooms they have. You may have to park down the street which is still $20 a day. This hotel is centrally located about 3 blocks from the southernmost bouy. About a mile walk to the other end of Duval Street, but the bus stops at the end of the block and is only $1 for one loop. This hotel was charming with its wooden floors, front porches, and high ceilings. It’s a bit loud when people are in the halls or using the stairs, but the AC works great and our room was very big. My only wish was that they provided hairdryers in the rooms.

Great place in a excellent location!
It was a great stay overall. The front desk staff was friendly and accommodating. We were able to check in a 2:30 on a Saturday afternoon. The location was perfect. The hotel had a lot of character and was updated & clean. The only negative thing would be that the bed was a little too firm. The pillows were great, though.

Rip off Resort
The location is great. The rooms are mostly clean, walls are paper thin so you hear everything, and very well lit so there is no chance of sleeping in. They charge a parking fee, but only have 7 parking spots. They charge a cleaning fee, but never cleaned our room and didn't give us fresh towels on our 4 night stay even after asking for them. They have a resort fee, but no towels available by pool, gym was locked and closed, bar was locked and closed, breakfast was cereal and danishes. I didn't even see milk for the cereal. No juice, horrible coffee, limited creamer. The room had no thermostat to control temp. Little to no water pressure. I'll just stop at that....
