A very convenient location - 5 minutes from Sagrada Familia, walking distance to Gracia and a few steps away from a metro stop - in a very stylish space. It was quite comfy (the softest beds we've had in a long time!) for our family of 4, for our one-week stay. (Might be tight is you have a lot of luggage or need to hang bulky coats). Plenty of hot water, a very useful washer with dryer capability, warm blankets, kitchen and eating space. Super communication (even during the holiday), and friendly check-in. And a lovely shop with coffee and handmade chocolates right across the street - not to mention the gorgeous architectural hospital around the corner.
Know that the building is located on a bus route and over a metro station - we did not find the noise to be too disturbing, but if you're a light sleeper it might wake you. (Ear plugs would help). Also know that while many wonderful amenities are supplied - kitchen items, towels, iron, drying rack, shampoo, coffee pods, dish and laundry soap, some are in surprisingly limited amounts. Understandable with the coffee pods (it's a Nespresso machine, by the way, so be sure to bring some pods of your own or you can source them near Plaza Catalunya), not so understandable with the toilet paper. We were given only 3 rolls for 4 adults for 1 week, then after several calls given 3 more which we were told was beyond our limit. We had to buy more toilet paper in addition. Not a big expense, but something of a hassle on vacation when the presumption is that such an amenity is supplied reasonably for length of stay and number of persons.
But all in all, this is a very good value apartment in a very good location, super clean with just about all you would need. Recommended!
