Getting to the point: my stay was just ok and there is probably better.
We did not meet Sofia, but dealt with her mother Maria who was very kind. I wish they would have just provided us a map from one of the tourist offices as that's what I've received from all hosts in my 4 wks in Europe. They're free.
Communication was great and sometimes excessive but the space in which we stayed in was clean overall. A few ants near the window and a bug or two in the shower. But what do you expect when windows stay open for lack of AC. The fan on the wall right in front of the bed was nice to keep cool.
The bed and linen was also clean as all we did was sleep and shower in the apartment.
CONS: it's on the 5th floor and even without luggage it's really a workout walkin up the steep stairwell. The 5th floor with no elevator is mentioned in the description but it's not mentioned how the lights are super dim and the lights flicker. The entire stairwell is dirty and not clean and honestly looks like it came straight out of a horror movie. I was worried about falling and was honestly not looking forward to seeing the living space after seeing the staircase.
The location is really close to Ramblas and the metro which was cool but you also subject yourself to literally being asked if you want weed or cocaine at least twice each time you walk to ramblas (each block). It was sketchy and I think there are nicer areas where you might be 5 minutes further from Ramblas and have a nicer experience.
Although our host was nice, overall the stay was just okay. The stairs to 5th floor with hardly any lighting, sketchy stairwell, drugs being offered on the same corner every block made the stay not as pleasant as it could've been. I would not stay here again. The metro system is too convenient to settle for somewhere just because it's close.
