Mireia's place was conveniently located, comfortable and very clean. We found it the ideal location for our short stay in Barcelona.
The only small negative we had is that when we arrived at the address we weren't sure how to get into the building or which floor we needed to be on. I think this could be communicated prior to arrival. The host also gives a very thorough tour of where every item is located which I'm not sure is entirely necessary as you could easily look for whatever you needed.
The apartment is very comfortable and has everything you need. I would absolutely recommend.
