I can't say anything on the localization because the apartment is very well located in La Valette. Same for Franco's kindness and precision of his guidelines/help.
Nevertheless, some things are really embarrassing.
The 2nd bed (couch) is not adapted for a bed, really uncomfortable.
The bathroom is dirty and the shower window is broken. Toilet are not clean and impossible to use hot water in the sink.
Needs more comfortable pillows and beddings.
No performing heating system which means during the winter it is really cold.
For whom are sleeping in the living room the bow window bring noise (a flat is under renovation, cars accelerating in the uphill..even the rain). It means in addition to an uncomfortable bed it looks like you are sleeping outside (cold and noisy).
To resume, the whole apartment need a real cleaning and some improvements to enjoy even a few days.
I don't recommend during the winter and for a long period.
Hope I helped to avoid any deception for your next trip.
