Andrea's place is very well located and is close to a lot of restaurants & tourist sites. You can walk to these or take the metro or bus.
Andrea makes herself accessible despite her busy schedule. We had missed our connecting flight & Andrea was extremely accomodating & understanding of the situation and ensured we didnt have to worry about accommodation or check in time etc.
The place itself is a beautiful penthouse with all the basic amenities needed. We were mostly out so didnt use these much.
A great place to stay overall if you are in Barcelona.
