The apartment looks very special, provides you with everything you need and is due to its central location a perfect place for discovering Rome. The hosts are also very friendly and helpful.
However, one has to notice that there is no daylight at all and that the whole apartment is relatively humid. Despite the dehumidifier, air remains humid so that clothes etc. feel likewise. I would therefore not recommend the apartment to people very sensitive to humidity or those with breathing problems.
Overall, though, we enjoyed our stay!
