The owner of the unit was very good at communicating and answering my questions before booking, and we were able to add an extra night, which was really helpful. He also gave us a different unit which would work better for us, needing 2 different spaces for sleeping.
The unit is very near the metro, which was great. Though future guests should know that this area of Barcelona is VERY hilly with steep streets. There is a full grocery store that requires walking up and down a few steep streets. Future guests should be aware.
That being said, I was very disappointed that we were only provided 2 small rolls of toilet paper for 2 people for 6 nights. And there was only one bag for trash. I did reach out with a message to the owner requesting additional toilet paper, but he said that after we used what was provided I would need to get my own toilet paper. I feel as a guest that I should be provided the basics for the number of nights booked.
