My friend and I had a great one month stay in this apartment! When we arrived everything was very clean and organized, which helped us feel at home immediately. Overall, the apartment felt very newly renovated, which was also nice! The two bedrooms are really nice with their own small balconies where you have direct sunlight for about 1.5h around lunch time each day. The kitchen was very well equipped and in general we had everything we needed (apart maybe from a table on the balcony, which would be lovely, as it is actually big enough to sit on it).
Just to be aware, you have to sign a contract before they allow you to stay in the apartment and it would have been nice to be informed about that before and get a chance to read it before. In general communication was a bit hard sometimes, and we would have wished for some quicker responses in some cases.
Also if you are planning on working from home, be aware that the living room is actually quite dark, as there is only one small window. However, it is very cozy with a nice sofa in the evenings.
We especially loved the apartment because of its location! Poble Sec is amazing and being just at the bottom of monjuic was great! Sant Antoni, Raval, Gotico are all easily and quickly to reach walking and there is also a really nice pedestrian street full of restaurants just a few minutes walking. We felt very at home in the area and it was hard to leave. Overall, we had a really good month in the apartment!
