The Bettoja Hotel Mediterrano is quite lovely. The decor in the hotel is semi vintage and beautifully placed. I loved the fact that the hotel is located a few metres from the main Roma Termini train station and other attractions like the Colosseum, Trevi Fountain, etc, are 10-15 mins walking distance away. There are also very nice restaurants all around the hotel. I would recommend a visit to the restaurant opposite the hotel, the food is fantastic, one of the best Italian restaurants we've ever visited. The room is well apportioned, the bed very comfortable and the bathroom is fantastic.
There were two negative experiences for us. The first is the attitude of the front desk staff. They come across very gruff and grumpy. They appear to have forgotten that they're actually at the front desk to assist their guests. The second is the poor quality breakfast. It is very average, to say the least, for the standard of such a hotel.
My overall rating for this hotel is 4 because of the negatives mentioned above, it would've been higher otherwise.
