I can say only positive things about this place. It is more than a suit, it is practically an apartment what you share with Sebastian. Who is a very nice person, host, helps a lot and if you have any wish he has no any problem to give his best services.
There are better location in BCN but for this price it is absolutely ok. You can reach easily coming from the airport (6 minutes walk) and metro L1 and L5 are in 7 minutes. So it has excellent public connection. Nice bakeries, greengrocers and small suermarkets everywhere.
Only thing I must tell, since your place is in the attic the ceiling is a little bit low. So just carefully with your head at the door frame. But because of this it is very cosy.
I spent great time here, more than vacation and honestly can highly recommend! So just go ahead to book, but leave some gaps for me! ;)
