I would say that our stay was pleasant overall but there were some pros and cons.
PROS:
-Fantastic location!!!
-Fairly quiet for the city center
-Host was friendly
-Easy check-in and check-out
-Comfortable bed
CONS:
-The bathroom was extremely uncomfortable for us. The shower and toilet are very close together and it was difficult and uncomfortable to use.
-The host forgot to leave toilet paper and had to bring us some which was a bit inconvenient upon arrival.
-The flat in general just looks a lot nicer from the pictures. Don't get me wrong - it's very cute but it's a bit more cramped and older than shown.
Overall, I would recommend it as a budget option for a short weekend trip but it wouldn't be my choice for a longer or second stay in Sevilla simply because of the bathroom.
