Alessios place is really nicely located if you yuo want a vibrant nightlife expirence, this was one of the best locations i could think if in Trastevere.
the reason i can only give the appartment 3 stars, rests on these points:
The combined refrigerator and freezer was so over frozen that the door could not even close due to all the ice. and the freezer was in dire need of a de-icing.
The showerhead had been descaled so much the the gaskets were completely broken, so the showerhead was more or less useless.
The main problem though for my part, is that the appartment only has 2 very small windows. None of them nearly large enough to fit a human being through, and thus, no use, if a fire made the main entrance inaccessible.
The very small windows also meant that the air circulation in the appartment is not very good, specially not in the bedroom, that has no windows, and are in the very far end of the appartment.
Save for these issues, the apartment as a very nice place to stay.
