We had a really great stay at Martas Guest House. The service was great, and the staff was extremely kind and helpfull! The room was clean and bright and the hotel was located near the metro, good restaurants, the vatican, and if you are up for a small walk you can reach most of the sights in Rome by foot within 45 min from the hotel. There is wifi at the hotel but the connection is not excatly great. Also, the ad for the hotel said that there was a/c in our room, but we only had a ceiling fan. The breakfast is OK, nothing special but alright. All in all, we were very happy with our stay and will definently recomend it.
