We were excited about the possibility of renting this flat from the first time we saw it, and we had a great experience there! We were very happy with all of the communications with Yasmine, our contact; she responded quickly and helpfully to all of our questions, including getting the three of us set up with door access using the Nuki app, which allowed us to unlock both the external and internal doors with a smartphone app.
The flat's location is practically perfect; the flat occupies the first floor of a building, one block away from Placa Reial and about a block away from Las Ramblas. There are TONS and TONS of dining and drinking options located very close to the flat. If you're someone who enjoys a night out and is looking for a lovely place to stumble home to, this flat is ideal. And if you're someone who's interested in getting lost among the cozy and quaint ancient alleys of the Barrio Gotico, you'll also be very happy here.
The flat itself is great; it is older but well maintained, with two large bedrooms and one smaller one, a nice lounge with large flat screen TV, a nice little kitchen with dishwasher and clothes washer, and great air conditioning. Both bathrooms were tidy and functional. The AirBNB photos were accurate, and the space is quaint and lovely. We were particularly (pleasantly) surprised at how well the windows and shutters kept out the street noise. (There was a lot of street noise on weekend nights, but we literally could hear NOTHING once we closed the windows and shutters.)
Our only (minor) quibbles about the flat are that the Wifi was painfully slow, and the beds were not super comfortable. We brought up the Wifi speed to Yasmine, and she asked us to reboot the router and let us know if that improved the speed; it did not. The fastest download speed we saw was 0.2 MBPS. It's not a huge issue, since we weren't in the flat all that much.
On the whole, we really enjoyed our experience there, and we'd gladly return for a visit in the future; we can recommend this flat enthusiastically.
