Really nice flat with everything we needed. Comfortable beds and plenty of hot water.
Situated in a convenient location for the Metro into the city. Or you can walk. It took us about 30 minutes (we're in our late sixties so it probably wouldn't take as long for someone younger and fitter).
We didn't meet Elizabeth, but Tony was really helpful when my phone stopped working.
He also booked a taxi to the airport for our early morning flight.
I would definitely stay here again if in Barcelona and would recommend.
