I really would not recommend this place to elderly people because of many narrow and steep stairs (there is no lift!). Besides, it's very noisy during the weekends (at night you hear loud music from the pub downstairs). The showers cry out for a quick renovation. The breakfast is OK, but it is not served on Monday. This guesthouse has only two plus-points (except the price): it is five minutes' walk from the railway station and the internet (WIFI) is for free.

I really do not recomend to reserv a room there, you might have to sleep under a bridge.. They cancelled my reservation, just 3 days before my trip to holland, FOR NO REASON!. They sent me this email: "Hello, we councel your reservation Pension Tivoli"
FIRST: is councel a word? NO! when i asked what they meant they answered:
"We stopped your reservation"
This is not professional and not FARE at all, i had to call anywhere in Groningen, to find a place to sleep.‎

...and as such I rate it very highly. OK, you do indeed get what you pay for, but if you are just looking for a place to sleep then this is it. I have not found a cheaper place to sleep, where you get your own room, as opposed to sharing a dorm with between 8 to 16 other people. The services are basic, but adequate and the cleaning staff are present each day.

I have lost count of the times that I have stayed here, I really like it. They have often found me a room when I have turned up late in the evening. Only one time, over Easter, did I have to leave, as I hadn't reserved the room beforehand, which was entirely my fault, so they can't be blamed for that.

If there is a cheaper room anywhere in Holland I would like to know about it.

A simple breakfast for 5 euros is available too.

We were looking for a budget hotel and we did not expect much. So the small and old room was no problem for us. But it turned out that the toilets were outside the rooms and in disgusting state. That is even for a budget hotel not ok.
Furthermore we soon found out that it was almost impossible to sleep in the rooms, because the windows to the street had no sound insulation at all and the cinema in front of the pension is very noisy up to 2 am. In the morning then at 6 am the construction workers, for which this pension served obviously as a dump at that time, got up and one could again not sleep.
So we moved out after that horrible single night and cancelled the following nights. We rather payed more in another hotel and were able to sleep then,
So do yourself a favour and avoid this dump unless you don't need to sleep.
