Hello Mike,
I live in Barcelona and I would really recommend going to this awesome city. There is so much to do in this city!
If you love architecture you will fall in love with the city. You can find so much and you really should take a look at the buildings of Gaudi. Go to Casa Mila, the Sagrada Familia, Casa Batlo and of course you have to visit Park Guell.
Besides the architecture it´s a good place for shopping, drinking at a cafe, going out and just enjoy the warmth.
You really should take a walk over Las Ramblas.
Trust me you won´t get bored there, there is enough to see.
What I´ve heard about the hotel it is quite good and the rooms look wel.
