Phil and Fiona were great and attentive host! Communication was fantastic throughout the stay; Phil coordinated the check-in to meet us in person and gave us a quick rundown of the apartment and afterwards Fiona checked in multiple times to see how we were faring. The location of the apartment was perfect, centrally located in Barcelona near the Gothic quarter, about a 5 min walk from the multiple metro stations and shopping/groceries and about a 12-15 min walk from the Las Ramblas.
The apartment itself was very cozy and comfortable, with a nice homey feel. Unlucky for us, we happen to visit Barcelona at the end of the massive EU heat wave. The apartment is on a higher floor and even though we closed the windows/shades, it got pretty warm every day. The multiple fans Phil and Fiona provided did help, but frankly we just couldn't enjoy the apartment as much as we otherwise would have because we were so hot (cooking especially).
The size of the apartment is perfect for our family, (2 adults and 2 children) but that is probably the max number of people to fit comfortably. Washing machine is a nice bonus, but note there isn't a dryer so plan accordingly for time needed to hang dry clothes (they do have a very nice clothes rack). The shower could use some TLC, but otherwise else in the apartment met or exceeded our expectations.
All in all, fantastic hosts and primo apartment location! We would definitely stay again but likely in the autumn or winter seasons when the weather is a bit cooler.
