Mercedes's apartment is so authentic and has so much character, I felt as if I were in an artist's studio for some reason. The bedrooms are very bare necessities but as you are most likely there to visit, you really just need a bed and a shower so it was fine. We had the room with an private outdoor balcony accompanied with an outdoor shower, so that was very unique. Speaking of outdoor balconies, Mercedes's terrace over looking Placa Reial is incredible! Worth staying here all together.
She was also very nice to leave drinks and snacks out in the kitchen for the guests. Her cats are adorable but they will scurry into your room if you are not looking. Didn't bother me but something to note if you are not a cat person. The shower/toilet area were nothing extravagant but definitely got the job done. There was a fan and heater in the room as well if needed.
Mercedes's check-in was no problem, just have to be prepare to walk up the stairs all the way to the top floor with suitcases. So worth it once she takes you out to the terrace. She was very friendly and gave us many recommendations and answered all our questions.
Personally, I would stay here again but if you are more of the luxurious type then I probably would not recommend this place to you.
