We enjoyed our stay in Centro Ariane. Originally there was supposed to be a baby with us so we called in advance and they had organised a baby bed in our room. Also we were able to organise it so that my sister could check in before we arrived even though the reservation was on my name. So very good service and helpful staff!
The room was cozy, nothing special. Shower curtains were slightly moldy and the towels were changed daily even though they have an environmental note that they will only change them if towels are on the floor (for me the environmental side is important so this was a minus so I cancelled cleaning for the whole stay).
Breakfast was plentiful: breads, eggs, cereal, coffee, joghurt, fruits..
