Hotel H10 Universitat, Barcelona

As to where to stay in Barcelona... Well, since you have many many choices (which makes it easy to find at least three or four nice hotels at a good prices) I think the most important issue is surely the location of the Hotel so my advice is for you to choose one in the center of the city.
I stayed at H10 Universitat Hotel and, without any doubt, I would choose it again. Very near to the Plaça de Catalunya this hotel is very central and, besides having all transportations available just a few footsteps away, one can also easily walk to Las Ramblas and to the Passeig de Gràcia.
Finally as far as the bedroom goes, although it was in fact a little small (some say, shoe-box size), it was impeccably clean. About the food, no opinion (booked only the room) and about the staff, they we're always both friendly and efficient. Loved staying there and I do recommend it!

Hospital de la Santa Creu i Sant Pau, Barcelona, Spain

Another place you might wanna check out in Barcelona is the Hospital de la Santa Creu i Sant Pau (in English, the Hospital of the Holy Cross and Saint Paul).
The several buildings that compound it and the surrounding areas were designed has any hospital should be - a pleasant place where people go to recover - just admire the beautiful gardens in the photo bellow.
Although the place is classified as UNESCO World Heritage Site and there's another new hospital nearby all of this old Gothic style pavilions are still in full function.
Above a few photos with some of the delicious details of the buildings and an interior picture of the main hall.

Merry Christmas!!!

Templo Expiatorio de la Sagrada Familia, Barcelona, Spain

Still in the Sagrada Familia, today's photos are from the Nativity Facade which is located in the East side of the Cathedral. Dedicated to the birth of Jesus the sculpture work present in this facade is simply unbelievable.
Sculptured in the stone all around are many, many images, the majority of them representing the Nativity Scene - in the photos bellow you can see some of them in detail.
I would also advise you to take the elevator and climb to the top of the Nativity Towers. It should only take you about half hour waiting and it's worth it - both the pictures bellow, and the last one from the previous post, were taken there.
When descending from the Nativity Towers - which as you can see above will take you a while :) - pay attention to the spiral staircases design. Like many things inside the Cathedral (yet to be posted), they were inspired in nature forms.
