The pictures and description of this loft are very accurate. Very spacious, well equipped and comfortable. You should know that the bathroom is very small, but that wasn't an issue for me (I am also 5.1)
Gracia was good area and with public transportation, you should be totally fine getting wherever you want to go.
Xavier was great host! He was very attentive and accommodating. Very responsive over text or whatsapp, so if you have any question while you're there, don't hesitate to ask.
Overall, I was very comfortable!
