I stayed for a weekend (Friday to Monday) and I must say that the noise from the sportsbar across the street was unbearable, especially saturday night!
Really a pity, as everything else was nice. I really liked the lounge/veranda for a coffee break and the small library on the first floor. The staff was very helpful and professional - very quick check-in and -out, and good breakfast.
I can recommend to stay if you are able to get a room away from the square.

I loved this hotel in the middle of the square in the small town of kalmar. The location was great for walking to the old town or the cathedral square. The downside may be all the noise if you like to get to bed early and if you get a room facing the square. They give you earplugs in your room but it didn't bother us since we went to bed after the ten o'clock end of the show. There was free wi fi and a computer free in the hotel for use. The room was a decent size with a small couch and two windows that opened. There was also a fan supplied since there is no air conditioner. The breakfast was fabulous with gluten free bread, eggs, freshly squeezed juice, yogurt and fresh fruit. There were nice chairs and couched for lounging. There is also a tearoom tomcheck out, delightful for a takeaway lunch , tea or dinner. Apples at the front desk. Free music out front your door.

after we had moved out of the skansen hotel on oland only an hour after check-in (see review for reasons) we drove back to kalmar and got us a room in the frimurare hotelett in the center of kalmar.
parking between 6pm and 9 am is free in the streets.
the receptionist was very friendly and let us check the rooms ourselves. we finally ended up in a quiet room (#14) on the ground-floor, facing the green hill behind.
the room is spacious enough, furniture makes a decent impression. only thing that might get annyoing is the strange sound that is turned on anytime somebody enters or leaves the lobby of the hotel.
but the receptionist leaves at 10 pm and switches it off, so the night then is quiet.
the hotel is very centrally located at a square that on nice days might be quite busy and loud at night. some of the restaurants there serve food outside as well.
but there are rooms not facing that square.
from our point of view, provided you get a room less prone to being swept by noise, the hotel is a deal. but they let you check the rooms before you move in - friendly staff that is.

there are some restaurants around, and even one that offers mexican food - tacos, soft and hard and many more tex-mex stuff, all you can eat style (incl. free beer ;-), the place is called ITALIAN.

The service was wonderful. This is a family owned hotel and the staff is very helpful. The breakfast was the best variety and quality of food that we had seen over the 3 hotels that we stayed at with breakfast included. We were hesitant about stopping in Kalmar but we loved the town and are very happy we did it. We spent the morning walking thru town and then drove around Oland a bit (pretty open but a nice detour).
Also the staff recommend a restaurant that isn't in Trip Advisor's list...Lamagartan 10. It was one of our best meals in 10 days. The staff their was also very nice even though they were busy and we were not assigned a specific server. I would highly, highly recommend a stop in this town if you are hesitant about it.
