Stay somewhere else! This flat is underwhelming at best and
THE HOST HAS A VILE ATTITUDE
I will keep this short and to the point, but the gist is that there are countless better places to stay in Barcelona. For starters this flat is not as nice it appears in the pictures. It is much smaller than it appears, only has 2 bedrooms as the 3rd one is just a bed hidden behind a screen in the living room, only has one tiny heater (not even close to sufficient in the winter) and had a funny smell when I arrived. On top of that the neighborhood has very little to do, is lacking in personality, and is a 20 plus minute commute to the city center.
Disappoint of the flat aside, we were appalled at the attitude of this host. She sent conflicting check in times and when I arrived on time according to the initial check in time that she sent her reply was "Look at your watch it's not 15h yet." When I got her on the phone she yelled over top of me, and refused me an opportunity to speak. With no regard for the fact that I had been traveling for 27 hours at that point, she told me to "relax, you are on vacation, it's only 50 minutes." I won't go into more details of her condescending and rude attitude but I have several more emails from her with inappropriate comments and insults from her. At one point while yelling at me on the phone, she handed that phone off to her husband (who was very pleasant, I have to admit) and she continued yelling in the background. If this person had even the slightest bit of customer service ability this entire episode could have been resolved without incident, but she does not. She has a vile and condescending attitude.
Save yourself the disappointment and stay somewhere else.
