This place is only a few hundred metres from a metro station on the main green metro line going into the old centre. And you can easily walk up to Park Guell (believe me, the street escalators are an experience, and a bliss). So you can stay here in a very quiet and “real” residential area of the city, and still be conveniently connected to the must-see highlights of the city. By the way, you do have stunning views from the terraces (yes, several), all the way down to the sea.
The place is cosy, and the pictures do it justice. Downstairs you have one twin room (access through the kitchen; use the corridor toilet) and one double with a nice en-suite bathroom (with excellent shower; we had some issues with the flush of the toilet). Upstairs there is one single room (though you could put a second be there; very tight, but possible) which has access to the main terrace (from where also the stairs to the top terrace), and then there is the Master bedroom with a double bed and two twin beds (and private terrace and en-suite bathroom with nice bath and correctly-flushing toilet). All beds were really nice and we slept well. So, if this bedding arrangement fits your group, then this is really a nice place to stay.
The kitchen is convenient and functional, with the basics when it comes to cutlery and cooking utensils/pots. If you plan to mostly go out to savour the great local kitchen, then this kitchen is more than enough for your breakfasts (including Nespresso machine!); if you plan to cook full meals, you may run into some practical challenges.
We really liked our stay, and quickly felt at home. The welcome and local support by Francesca was great (always only an SMS away), and Maria kept communicating so well via AirBnB messaging.
