This home is ideally located in the heart of Barcelona next to a Metro station, which also doubles as a train station to the airport. We were a family of five and this apartment had plenty of space for us. The internet was good (not great) with 11Mbps download and 10Mbps upload. There are nice windows that look out over Castillo Batllo and the main thoroughfare. The home was immaculate. I really enjoyed staying here. It is one of those great AirBNBs where you visit and everything works just as you had hoped.
My only two quibbles were-
1) The property manager (not the homeowner) assaults you for Eur20 as soon as you walk in and demands it must be in cash and must be paid immediately. It feels an awful lot like a third world police officer shaking you down. The beauty of AirBNB is that everything is taken care of upfront. I would recommend raising the price by Eur20 or covering this cost from the rental proceeds rather than this strange cash demand.
2) The fuse blew in the back rooms twice while we were there, which is not a big deal, but labeling the fuse box would save everyone a lot of grief, including the homeowner.
