Everything was clean and as described. The two balconies provided enough daylight. The location is super central, right next to the gran via. However, it is a bit noisy, especially because the windows are very old and not made of glass. With earplugs, I could still sleep without any problems.
As I booked quite spontaneously (1 hour before), I was especially grateful that the host reacted so quickly and that I could get into the flat.
Overall, a pleasant experience and I would book with Diogo again.
