There were positives and negatives to this apartment. On the good side: fun artwork, good kitchen (with proper caffetiere), nice bathroom with power rainfall shower, excellent central location. That said, I would not stay here again.
The apartment was incredibly noisy, and caused me to sleep very poorly all week (especially problematic as I was in town for work). The apartment is one that has been adapted purely for Airbnb use, something I have not encountered before (previously on the site I've always stayed in people's homes). As such, certain fittings had been made cheaply (the main door handle to the outer door fell off during my stay), and there was a strange locked door (presumably originally the main door to the apartment) leading off the studio. From the sounds outside I imagine to led to an outside corridor with lots of other rooms leading off it - door bangs, footfall, and even clear conversations can be heard all night long - especially from 7am onwards. The heater which powers all apartments is stored in this studio, and emits a loud electrical hum that goes on and off all day and night depending on use throughout the building - also hard to sleep through! Finally the studio is warm even at this this time of year, but it is impossible to open the windows onto the street without a huge volume of noise (this one I minded the least as it was at least within one's own control!).
The location is great, Luigi a good host and clear communicator, and the rent is cheap, but I think ultimately not worth it unless you are a particularly hardened sleeper.
