We stayed here for just over a month and really enjoyed the apartment. We felt at home as soon as we entered the apartment, it is very modern and clearly newly refurbished which is reflected in the photos. There were issues with the doorbell which we raised and they immediately contacted us to say that someone would be over to fix it ASAP, an engineer arrived a day or so later and sorted this out without any hassle. We also asked for a washing line to be brought over as we do not like tumble drying certain items of clothing, the agency came over within a day with a washing line, other than that we had no problems whatsoever and any questions were responded to very promptly which made us feel very comfortable. The apartment is fully equipped with the latest equipment, the hob was really nice to use and the washing machine one of the latest Samsung models so we knew we wouldn't have any problems washing our clothes.
The apartment itself is very modern and the master bedroom was spacious enough for us, we used the spare room to store our belongings however there's more than enough space for more than 2 people. We live in Barcelona and know the city very well and therefore can attest that the location is perfect and you'd probably struggle to find better, you can walk everywhere from here however you have 3 Metro stations within a 5min walk, depending on the line you wish to take.
You can feel and hear the metro beneath you but after a day or so you get used to it and hardly notice it, a bit like living near a main road. I can't really think of many downside's other than that and we have already decided we'll be staying here again, this has so far been our best experience when using Air Bnb.
