We stayed for one week. Our room was prep't for just one person. Its two hotels with one reception and very busy at peak times. The Novotel rooms (called superior) were very good, big TV, good bathroom, clean, well maintained and comfortable. Breakfast offers a decent selection and quality. Within a 15 minute walk you can be in all the important places in the city centre and the station.
What spoiled our stay. I also booked a second room for Friday to Monday so our Polish family could drive to us. When booking both rooms I asked if they could be close (they have 2 very small children). This request was confirmed by the hotel in an email. On our arrival reception confirmed it was in our room notes. Going to collect the keys on Friday afternoon the second room was on floor 13, ours floor 16. Reception said sorry we cannot change it. Later after a conversation in Polish with the manager it was agreed we (without any assistance offered) we would relocate to floor 13. This meant two large cases plus all the shopping and Christmas presents we had been out and bought for the family plus the issues of packing - unpacking all over again.
Rooms are identical just furniture moved to open a put-you-up third bed. To add to my annoyance about one hour later and mid move a family arrived on floor 16 having just booked in. I had a word and saw it was identical to my second room. They had not checked in, so had management bothered to look, a simple computer change could have sorted it.
