I've stayed for two nights and three days at Polash's place.
The room is amazingly clean, and it is located in the core centre of Rome. I've liked the style and cleanliness of the room, together with the warm welcome by Polash and Alex that had made sure to always be available for any kind of need and quick to reply.
The place is very near to Piazza di Spagna, and Stazione Termini Centrale; thus, it has been very easy for me to visit and move around.
I will definitely come back if I will be in Rome again. I highly recommend their rooms.
