Hotell Stadsparken and its lovely staff outdid any expectations I had! I stayed for 3 nights, from Tuesday to Friday, and albeit the hotel was a little quite (it was in the middle of the week) it was cozy and relaxing. The rooms are well equipped and insulated - you do not hear any neighbors. It is very clean, and you can ask to restock as many towels you might need (I mentioned this as I read some negative comments about this. It is typical in Sweden, to save on water, to just leave a couple of towels in the rooms, and you ask them for additional when/if you need it)
The breakfast was the highlight. Both warm dishes like eggs, bacon and oatmeal, and cold cut dishes. For the one with a sweet tooth, there was ample waffles and croissants! Free coffee and tea was available at all times in the hotell.
Monday-Thursday they serve a lighter dinner for all guests - something I did not expect but was pleasantly surprised by. It was included in the price.
The location is perfect. It is less than 5min walk from the main central station. It is less than 2 min from another bus stop called Biblioteket that can take you anywhere. The area is very green and walking friendly!
Finally, the staff. I regret that I forgot their names, but they were lovely all of them. Always there to assist with the smallest thing, yet not in your face bothering you when you wanted your peace and quiet.
Next time I came back to Helsingborg, this is definitely where I am staying again!
