Cost: $151.50 Euros (3 Nights) 

P.s. As it is an apartment, there is no signs showing it.
Just look for the address and you can find a button to press at the entrance of the building. 

 Free breakfast is provided and you are free to use the kitchen.
Host is really friendly and he has a dog with him. 

 There are a total of 4 rooms in the apartment with 2 toilets which i think is sufficient.
Toilet is well decorated and spacious too! 

 Quick lunch over at an eating place just next to the apartment. 

 After which, we headed to where Montjuic Castle is located at.
To get there:
Go to Espanya metro station and take bus 150 all the way up.
There will be a map and stations at the bus stop for reference.
Alternatively, you can take a cable car up which we did not. 

Do take note of the opening hours to get into the castle for better view.
A pity that we did not take that into consideration and thus can only walk around the place.

 There are 2 views from the top. One of which will be the sea-view/ port. 

Thank goodness, it's still really nice even though at times the view is blocked by trees. 

 Another view, is where you can oversee the city of Barcelona. 

 Other attractions at the bottom of the hill.
I think this is the entrance to the castle.
There are different parts to the castle and if you want, you should spend prolly an entire day there.
