 I arrived 10pm at night and it was a bit dark to walk to the hotel from Sants Estacio not from metro exit I came out from the station and tried to find my way A bit feel insecure but I still feel safe 
 Near to the metro and bus as well as airport Sants Estacio even though it will take some time to the city centre approx15 20 mins Nice room comfy bed clean and provide basic toiletries A few small shops if you walk from Sants Estacio LIDL and Carrefour just around the corner
