Andrea and his roommates are awesome! Andrea has better Spanish than English, and one of his roommates speaks perfect English.
The room that they let you stay in is very spacious and clean, with a huge bed! Andrea let us use his kitchen and bathroom every day, and was very kind and gave us plenty of privacy while also being willing to interact with us often.
The location is about a 10 minute walk to the nearest metro. We bought a 48 hour public transportation pass which was only €8.25. Would suggest going to the duomo and navigli (spelling?) at night. Overall awesome stay and thank you Andrea!
