It is a charming hotel located on top of Porvoo just next to the church. It is a beautiful old merchant house renovated to fit a small hotel. The public areas of the hotel are absolutely gorgeous, I loved the lounge and breakfast room / party hall. There is a wonderful snack/coffee/tea station if you need a refreshment. Also the hotel room was nice, but not a favourite. An old house has it perks - so you have to be an old house lover to fully enjoy this place. I loved the atmosphere, the location and also the staff was super nice and friendly. Breakfast was absolutely excellent with lots of small and delicious details. Hotel Onni offers perfect old Porvoo-style stay!

Cozy restaurant/hotel in an old manor in middle of Old Porvoo-city. Basic rooms that served us perfectly - massaging showerhead was a big plus :) Finedining restaurant conveniently in floor below. Exellent breakfast. Will visit again 👍

Upon our arrival at the hotel room, we noticed that the room temperature was over 30°C. Due to the severely limited reception availability, where only one person is present and only until 4pm, and with check-in starting only from 3pm onwards, we didn’t have time to see whether the room would cool down to an acceptable temperature before the staff had left the premises. We left to enjoy a day in Porvoo and returned around 10 p.m. To our surprise, the room hadn’t cooled down even to a mildly comfortable level; it was still unpleasant. Since there was NO staff on the premises (and the restaurant in the same building is closed on Mondays), we decided to call the number provided in the booking, which was advertised for use in case of any issues. Upon calling, I was belittled and blamed for not contacting the “available staff” earlier. After I explained the situation, the only resolution offered was to leave the premises if we were not happy with the room, after which the call was ended. The staff member called me back a few minutes later to suggest turning the AC off and on again, which we had already done hours earlier, while confirming the settings were correct. The person on the phone also insisted they had NEVER had any issues like this before in our room. They promised to look into possible refunds or reimbursements the next day and to have staff check the room in the morning. The next day, a staff member (not the person I spoke with on the phone) came to check the room and confirmed that the AC settings were correct. They also acknowledged that the room was indeed hot. Upon check-out, the staff member mentioned that ALL rooms are connected to a single outdoor AC unit, which limits its performance and can cause issues with the settings. So, contrary to what we were told, they have had problems before. Avoid Hotel Onni, worst service I've ever experienced at a so-called "luxury" hotel. PS. no reimbursement was issued or discussed (despite prior comments).
