Here is my breakdown of this location. My wife and I stayed here for 30 days so we can give you a pretty detailed accurate review.

Positives:
1. Host is very good at communication. Checked in on us and was very timely in response
2. Location is great, walking distance to Las Ramblas, Public Transportation and also all the necessary restaurants and grocery store
3. Internet was reliable
4. Basic necessities for cooking are there. You have pots, plates, utensils, cups etc.

Negatives:

NOISE (UNDERSTAND YOU ARE LIVING IN THE CITY, BUT THIS IS NOISE THAT IS NOT RELATED TO NORMAL CITY LIFE)
1. Neighbors are way to loud! Every Thurs, Friday, Saturday and Sunday they would do karaoke at a very loud volume. The first night we stayed, they sang till 2am. I had to literally go and knock on their door and got into a non-verbal argument (I dont speak Spanish so a lot of hand gestures) This happened every Thurs-Sun for the full month. Eventually it got to the point where they sang till about 12am... In the apartment listing it states quiet time at 10pm every night but that is not the case.
2. Construction. The apartment across the street is going through construction so from 9am till 6pm everyday you hear massive amounts of rocks being thrown down a chute, so very loud
3. There is a marble cutting business very close so you hear a power saw cutting marble from 9am till 5pm everyday..
4. The bathroom window is located in the elevator shaft, so you hear all types of noises from there. We can hear people snoring loudly at night, babies crying, etc. If you want a place with less noise, then this probably isn't the right place for you

BAD ODOR
1. there is a really bad odor in the area where the washing machine is located. No matter what we did, we could not get rid of the odor, it smells like human waste. If you keep the door closed for the washing machine the odor isn't that noticeable

THINGS TO BE AWARE ABOUT-
1. The Bunk Bed. There is 2 small twin beds on the ground level. The mattress are quite slippery on the frame, so if you move, the mattress slides off the frame.
2. The upper bunk bed was more comfortable, but going up and down a ladder could be difficult for those who have physical issues.
3. The Futon/Couch in the bedroom has seen its share of wear and tear. If you use it as a couch its at the point where it concave into the middle.
4. If you are staying for a long time be prepared to purchase your own essentials such as toilet paper and laundry detergent
5. For us Americans the apartment is the 3rd floor (in Europe the ground floor counts as 0... so just be aware as you have to walk up one flight of stairs to get to the elevator
