Tivoli hotel has a great location, walking distance or a short bus ride, from most of the places you would like to go on a visit to Copenhagen (Tivoli Gardens, museums, food options, etc.). You can also hire bikes from the museum (which we did for a day, including kids bikes) from the hotel - this is the preferred way to get around by most people in the city!
Breakfast was good enough. A decent selection of cereals, breads, pastries, drinks, etc. Kids like the pancakes with different syrups. During our stay (Apr'24 school Easter holidays), there was always enough place to sit without waiting (we got down between 8.30 and 9.00).
We had adjoining rooms which had adequate space. Rooms were in good conditions and nicely decorated. We asked for a quiet area for the room on check-in and the staff amended with no probs. Note, you need to ask for the rooms to be cleaned (previous day by 10pm). Additionally, you need to specify you want a full clean, else the only the towels are replaced and bins emptied. The room gets a full clean after 4 night by default.
The pool was great for the kids. Has a decent shallow areas for walking around. Some nice lighting too. We went on a couple of evenings (after 8pm) and it was pretty quiet. Added bonus, there is a sauna too.
We didn't need to interact with staff much, but when we did they were friendly enough.
Overall, a great stay with no problems. I'd recommend.
