Javier's apartment was fantastic, it felt like a home away from home for us. The best thing is the roof terrace, just beautiful and fantastic views. It was nice to come home to this apartment every day.
The apartment is very safe and secure, also great location, seconds from the Metro so very easy to get around Barcelona. Located opposite is the Arena shopping centre, with a large supermercat on the ground floor. Very convenient.
You can catch the country line train direct to Montserrat from the stop right out the front. Highly recommend. Also you can go direct to Lesspps station and take a short walk to Park Guell, again, definitely worth doing.
There are some great restaurants located a short walk nearby which we recommend (were recommended to us by a local): Federal is great for brunch, Lolita was excellent for dinner, gets busy quite late so you may need to wait if you come late.
Short walk from the Magic Fountain which was quite touristy but lots of fun to watch at night, you can also see it from the terrace. During the day, walk right up the top near the Museum, you'll get some great photos over the city.
There is also a washing machine so very handy if you are travelling for awhile.
Highly recommend, we loved this place.
