We spent 5 nights in the appartment. We didn't have problems with finding it or with the stay. It is not very modern or renovated place, but you have everything you need there and it's clean. We can recommend it.
Good to know: You will need about 20-30 min of walking to the city center.
The problem with the shower was already discussed in other comments. :-)
Roberto is very nice, we met him only during the check-in. His English is not the best but we didn't have any communication problems, he always responded very quickly.
If you rent the car: you can park in the area (till 8am), but - you won't be able to find a free place, so better use a car park before driving around for hours.
It is possible that you share the appartment with other guests because there is a second room that could be rent. But you share with them only the living room. There are two separated bathrooms.
There is a lovely balcony you can use in the warm eveings for a drink or for dinner.
