Stayed here for two nights with our 1 year old.
Pros
Excellent location and transport links - we walked to the zoo, took a bus to the city centre and got the tram back to the flat. Was very easy and straightforward and all within a short distance from the flat.
Very clean
Provided a high chair and travel cot which was very useful
Good communication
Good value for money
Cons - mostly issues with bringing a baby
Noise - The floorboards from the flat above are very creaky when the occupants are walking around, which woke our baby up a few times.
No plug for the bath
Screw protruding from floor near the bathroom door - not ideal if you have a mobile baby.
Boiler - we lost hot water and had to restart the boiler as it had an error light, but that seemed to fix it.
