We highly recommend you stay in this amazing apartment! It's a lovely space, very clean and has everything you'll need for your stay.
The location is fantastic too - a couple of minutes and you'll be at La Sagrada Familia. There's also two supermarkets just around the corner which are handy. If you walk to Sagrada Familia, you can easily get a taxi and it only costs €6-7 to get to the centre of Barcelona.
The host was great at communicating with us quickly, we only had a small issue with check in. We recommend that you call (don't text) when you're an hour from the apartment so you don't encounter a wait before one of the hosts can meet you.
