We had an excellent time in Barcelona. Every night we got to come back to a nice apartment with plenty of room for 4 (six comfortably) and enjoy a glass of wine on the beautiful balcony. Vanessa was a most gracious host - even arranging for us to drop off our bags 3 hours prior to check in time so we could tour the city.
A 10-15 min walk to/from the metro gets you around quickly.
