I stayed at Eva&Jack’s place for 5 nights. A huge plus is the location! It’s literally three minute walk from Sagrada Familia! The place was clean and equipped (except for the knife - we couldn’t cut bread or fruits). The flat is dedicated for 6 people, but there weren’t enough cutlery for everyone. The place is very close to the street so it was a bit loud at night but it can be an issue only if you sleep with the open windows. The check in was a bit difficult with an application because out of 5 people I was the only one who got the key to the room so my friends could only get in if I was there. Overall I recommend to stay at this place if you’re visiting Barcelona!
