We spent only one night in this hotel, but were very satisfied with the room and location of the Celuisma Alisas. It was extremely clean (yes, almost clinical) and comfortable. The service at the front desk started off cool, but he warmed up eventually. Don't expect much and you won't be disappointed. We were pleasantly surprised!

We stayed here in the family suite as there were three of us. The place feels like you are walking into a hospital in terms of the hallways and we had to walk for a while to get to our room from the elevator. This place was very sterile. It had very thin walls and we could hear the people talking in the room next to us.
There was no air conditioning and it was very hot. There was breakfast for a price, but it was very basic.
I wouldn't recommend this place, but at least it was clean which is important!

Stayed at this small-friendly city centre for 3 nights with my partner and our 12 year old daughter in a large Family Room.
The room was spotlessly clean, comfortable, tastefully decorated with a huge bathroom with a walk in shower. The hotel had provided some toiletries which was unexpected in a 2 star.
The hotel staff were efficient, helpful and friendly and ther receptionists spoke English.
Breakfast (included in the room price) was taken in the cafe/bar adjoining the hotel. It was nice with fresh pastries or toast, fresh coffee and orange juice. the bar was reasonably priced and served food and drinks all day from 8:00- midnight.
Checkout was at 12:00, but you can leave your bags for as long as you need.
The hotel is in the city-centre, a 5 minute walk from the train and bus station. We took the bus from the airport, a 15 minute ride @ 1.70 euros, busses run every 1/2 hour.
Our room was opposite a lounge which had a couple of P.C's in it with free unlimited internet access, which meant our daughter could charge her i-pod and chat to her friends on MSN!
Santander was great, will certainly go back and would stay at the Alisas again.

I visited Santander for an International Conference (ICALT 2008) and I stayed at this hotel because some others were full. I really don´t know from were to start...the room was not clean, it smeled terrible, the carpet was filthy, it was noicy, no aircondition...and more..! Thank God I did not bring my wife with me..she would be furious that I would made her stay at this Hotel!!! Please DO NOT TRY IT.
In addition the Wi Fi din't work and the receiptionists had VERY HARD time to understand and speak any English!!
