Alex and Lati's place was good for a solo female traveler. Their apartment is in a good neighborhood and was not hard to find using the instructions Alex gave me before check in. It is a 5 minute walk from a metro stop, and a 20-30 min walk to the beach, Gothic quarter/Las Ramblas, or Sagrada Familia.
Lati greeted me when I arrived and was super friendly. I enjoyed talking to her whenever I ran into her in the common areas.
The room itself is as pictured. It can get warm in the room because there is no AC but there are 2 fans in the room that kept me comfortable at night. The wifi was sometimes spotty but I didn't really have a problem. The shared bathroom was very clean and there is actually also another half bath in the apartment which was convenient.
