The apparent is on the best possible location in Barcelona, hardly can be better.
The cleanliness should be better. There is an unpleasant smell coming from the toilet. On top of that, the cistern/flush in one toilet didn't work at all.
Staying in this apartment you are in the epicenter of the city and everything is very close to you, within a walking distance.
However, despite all the inconveniences, I highly recommend this apartment because its location, space and two toilets will bring you a very pleasant stay in Barcelona.
