Great place to stay if you're going on a holiday. Ideal if you're going to work from there, but only if you travel alone. Two people working together, having meetings, can be quite complicated.
Apartment has no doors at all inside, so all spaces are open and you'll hear each other if you have online meetings.
Place is very nice, well decorated, super clean and modern. Definitely recommended.
Few minor things I did not like:
* No doors, not even in the master bedroom
* Bit dark, as most of the light comes from a relatively small window in the hallway
* Privacy conscious guests, there are two cameras inside, one of them pointing directly to the living room.
* Water and electricity is not included and adds up to the final bill
Overall it was a great stay and definitely a superb if you're going to barcelona for holidays, but not ideal if you're going to work from there.
