My partner and I stayed with our two adult children and one 15 year old. For the price paid for the room, it had enough room for us all to fit comfortably without being in each others way.
There are stairs from the carpark, although if this is difficult you could go down the car ramp to the front and use elevators.
Room was very clean, although fridge did not work, which we did not require, and was reported during our departure.
Reception is also only open limited hours, so you are likely to have to receive key from lock box on arrival without face to face to ask any questions. We also received the incorrect pin to gain access to key, but was able to look back on emails with phone to find correct pin (last digits of booking number).
All in all, for the price you pay, the room is very good, the area feels safe and has the convenience of shops, restaurants and transport (CAT) close by.
