We spent 11 nights here. Communication with Jul was great, we did not meet him in person but he even quickly brought us additional duvet (as one was not enough for).
This is a cute little apartment in residential part of Barcelona. Location for us was great, but if you expect to be in gothic area or historical old town, this is not it. You can get to La Rambla in about less then 30mins.
Its great place if you are either single traveller or a couple and plan to stay a night or three in Barcelona. I can not really recommend you to sleep on the upper bed, as its moving, makes ugly sounds and is not stable and comfortable.
Our biggest problem was actually wifi - not just here, everywhere in Barcelona - connection was unreliable, slow and just annoying.
Anyway, we enjoyed our stay and we are happy that we could visit!
