Our experience in Maria's house wasn't good, it was very complicated since the beginning, the description from Airbnb didn't match at all with the house, my familiy and I wanted an entire private place (as shown in the description) and it was a shared accomodation. We were traveling with our two chihuahuas and at the beginning she was ok with it ( charging us a fee per pet per day, wich never has happend to us using airbnb) later she made a big deal after entering our room without asking and told us that she wanted our dogs to be only in the terrace and it was pouring rain, she took our dogs out, and called us very angry wich bittered our day.
The kitchen was locked after 22:00, although it was offered in the description as part of the accomodation. There is no TV in the room, wich was also offered. The bathroom sink wasn't working well and the water wouldn't go away, this was fixed the next day, wich indicates someone entered our rooms again without us knowing, the rooms given to us didn't have any lock making it impossible to have any privacy. Maria lives in the house, wich makes it unconfortable if you need privacy, she's very confrontative to the point of wanting to talk to us at midnight saying she was outside our room.
The thing that annoyed us the most was that she's not a pet friendly person, she even told us that our dogs "were sick" in a despective tone, just because they were barking on the terrace, she shouldn't be accepting pets at all, and she should have told us the rules of her house regarding pets before we made the reservation our dogs are part of our family and we treat them as equal.
We have stayed in several airbnb's around the world and never had any problem with the owners, Maria is intrusive and makes it hard to relax.
The good thing is that Sevilla is a beautiful place,but if you want privacy and peace, we don't recommend this house. We felt that the price didn't match the experience at all.
