Carpe Diem was very central and only around 10 mins walk to the main square and all the shops. Check in was extremely easy and fuss-free, the code to enter the door was texted to us a few hours before we arrived and we just settled into the apartment easily (without meeting anyone). The apartment was on the 1st floor, very modern, very clean. It had all the amenities you need - iron, hairdryer, cooking utensils, and 2 free coffee pods. If you wanted more, you could ask the ladies who were cleaning the rooms to get you some. We could also do our own laundry (in the washing machines) downstairs which was a big plus. The apartment also provided a clothes hanging rack.
The only one drawback was that there were some guests with babies (who kept crying) who made quite a lot of noise whilst they were in the courtyard downstairs. This kept happening during the day, so in addition to them being rather irritating, it was not all that peaceful as the noise travelled to all the apartments in the building. You had to shut all the windows to keep the noise out. There should be a sign to tell all guests to be considerate and quiet when they are in the common courtyard.
Notwithstanding, all in all it was a lovely stay at Carpe Diem and I would recommend it to anyone wanting a central place to stay at a a very good price.
