We certainly enjoyed our stay at this conveniently situated city centre flat. It was clean, secure, comfortable and tastefully decorated. The multicolored shower lighting was fun and the shower itself is so big you could have a shower party in there.
Federico dealt with us and he was a gentle, courteous and friendly liaison. On the downside, the spiral staircase, though initially quite novel, is a bit of a nightmare. It is a squeeze to use and I wouldn't think it would be safe for older people, those with disabilities or impaired mobility, or children.
Other minuses: there was no plug in the kitchen sink, the iron and ironing board were gummed up with the remains of somebody's melted garment, and you wouldn't really be able to use the cooking facilities as the only knife provided was a single breadknife. Also there was no tea towel and worryingly one of the electric rings does not turn off completely so it's always a bit hot.
Other than that, the place was a great stay. I would recommend it, with the above caveats
