I stayed for five nights, and I was upgraded to a larger “superior” suite on arrival. Check-in was at another Suites Murillo on Plaza de Santa Cruz, and then I walked for about ten minutes to the Suites Murrillo Catedral location - you will probably need to use Google/Apple maps on your phone to find your way through the narrow lanes. Comfortable bed, excellent shower, very clean, and in a fantastic location right in the heart of the old town, with many restaurants and shops nearby - the apartment was very well soundproofed, so don’t worry about noise. Daily cleaning is available, and they will replace the free water/beer/coke that you have used from the fridge each day. The kitchen did have a couple of shortcomings - there was no sharp cutting knife, and no jug or bowl for heating things in the microwave. I would definitely stay here again.
