The flat was as advertised. Clean, centrally located, and the tenant was helpful and courteous.
For anyone visiting Barcelona for the first time, you can get to this flat using the R2 from the airport located at Terminal 2. Take the R2 train to Passeig de Garcia train station, then take the L3 train to Vallcarca station. This saves you $30 and about 45 minutes (depending on time of landing and traffic).
