The BnB is centrally located and about a 20 min. walk from the Central Station Termini. From here, all tourist spots are within walking distance, you really doesn't need the metro or any other public transport. The accommodation and the service is good (thank you Anna) so the price/performance is OK. You can have breakfast inside (in a separate room) or if the weather is OK on the balcony.

If I have to mention one less positive point will that be that in the morning it is a bit noisy because the doorman opens up the gateway to the courtyard (and the 20th September Road is a very busy road).

Conclusion: I recommend this BnB
