What a great apartment! The beds are super comfortable, which is probably the most important thing. In addition, the place is super clean, and there are nice amenities such as condiments (including olive oil, vinegar, and spices) and kitchen equipment (such as stove top espresso maker, wine glasses, cork screw, pots & pans, plates, cups, glasses, and an automatic dishwasher), as well as a nicely equipped bathroom containing shampoo, soap, and body wash, plus a washing machine for clothes. Nice layout and very spacious and comfortable for our our family of two adults and two kids. Our younger son loved having his own room with a balcony!
The neighborhood is great. Ten minutes to La Rambla and El Mercado de la Boqueria. One block away is Carrer de Blai, where you can find dozens of lively restaurants serving pinchos, which are so much fun! If you like exercise, you are in the shadow of Montjuic and can hike or jog to the top in a half hour or less. There are buses and a subway stop close by, as well as lots of super mercats open at all hours.
As is the case in much of Barcelona, people stay up late and roam the streets making noise. If you go to bed early (before 4:00 am) you may hear this activity and it might interrupt your sleep. But if so just remind yourself that one of the reasons you came here was to experience this sort of culture!
Over all, we loved this apartment and are very glad we stayed here. We would definitely book it again!
