For starters I don't have a lot of experience in staying at Airbnb's with the host in house . So I will give you my pros and cons.
Pros: Sylvia's place is in a great location with a neighborhood vibe, and the food and restaurants in the area were so many to choose from and all good price ... definitely eat in the area before choosing to go to the main Olympia area where all the tourists go… Everything is double price there . The view from the balcony is even better than the photographs show. Sylvia was as friendly as can be. Very welcoming to her home. The room available with the balcony view I was very very pleased with, it was cute simple clean nicely decorated .there is also a park directly across the street which you can view from your balcony, and at night time is amazing view of the sagrada familia church.
Cons: upon arrival, The address listed was not the actual address to the location. So when you get to that location I am Magine is when she directs you to the actual location ....or for some reason that's what happened with me. There is no elevator, and she is located on the second floor but it's actually more like three stories of stairs for some reason , so for someone with a lot of luggage this would not be doable . Once I got settled, Sylvia gave me the rundown of what I needed to remember throughout the house to make it a livable experience for her. She is sensitive to noise, so she thoroughly explained how I need to turn the knobs on the front door and then hold it a certain way to open it so that she doesn't hear the noise because her bedroom is right next to the entryway , this also applied to how I lock my bedroom door and I turn the latch, they were quite a bit of rules to remember to make it to where I didn't caused disturbance . I almost considered not going out that evening because I was afraid I wasn't going to remember all the rules . I arrived sick and had a cough & worried I was going to keep her up - which she did say she is sensitive to noise and she recommended a tea that would help me. The place itself was nice but a bit cluttery, and cleanliness & dust could be improved in the bathroom ...
Overall - The view was great., i recommend if you are a quiet traveler and don't mind being extra cautious of noise..and would like to visit with the host in the evenings.
