Me and my fiancé where in sergio's apartment for about 16 days and it was such a bad experience that left us really unsatisfied and frustrated.
First of all, he promised he would clean and sanitize the place before our arrival and when we arrived the apartment was severely dirty, there was still half consumed food left by previous people all over in the fridge and around the place, which is quite disgusting and dangerous considering the pandemic going on.
All the supplies and furniture in the house are old, broken or half broken.
There is only one pan in the house that is good enough to cook, all the rest of them are rusty and broken and the stove barely turns on.
The floor was dirty and the main bedroom got a weird bed that is made up by 2 thin mattress one on top of the other.
The bathroom pipes stinks so much that we had to get some ambient deodorant to try covering the odor.
The worst part was being constantly bothered by some people ringing the bell insistently every day, clearly looking for the owner, not to mention the struggle to make the hot water work. Shower is basically a Russian roulette where one time you get hot water and the other 10 times you don't.
During our stay we even experienced issues with the electricity, the power went out only in the apartment so we couldn't recharge ALL our electronics, the fridge wasn't working of course and this forced us to trash all our groceries.
We asked to the owner to address all these problems or partially refund us after all of this but he wasn't helpful and avoided the questions and never refunded us.
I suggest you to do not stay in this place ever basing on the experience me and my fiancé had.
