We stayed at Relais le Clarisse in Trastevere in 2019 and enjoyed it enough to rebook for our upcoming stay in October later this year. We liked the location in Trastevere but also the proximity to cross the Tiber and tour in the city with a short walk. We also really enjoyed Trastevere itself with it's many shops, restaurants, bars and just overall vitality. The hotel itself is quite simple and I think it will depend on how many amenities you are expecting. We enjoyed the simplicity of the check-in, the courtyard open for all to enjoy and the really dependable breakfast option to get our day off to a good start. If your teenage daughters are young teens it may not have the right ''vibe'' but if they are older, they would probably love the ''vibe'' of Trastevere. We are an older couple so that wasn't so important for us, but as our generation would say, 'it is a happenin' place'. At Le Clarisse, you might want to read up on the room availability and try to book in the main building. I seem to recall issues for some folks who booked in the 'annex.' I cannot comment on Hotel Smeraldo.
