We are full time nomads and stayed here over a month; loved every minute of it.
First, Marianne was a gracious host and communication was flawless; could not ask for more. The flat is spacious and was spotless for our arrival. The location is a minute from La Rambla, Placa Catalunya, the Gothic quarter with easy access to the metro. The kitchen was provisioned for everything needed when we cooked for ourselves. Internet was rock solid as it was up 100% of the time and speed was outstanding; 50 MB down, 10 up. Comfortable bed, nice shower.
I look forward to staying here again when our travels take us back to Barcelona.
