Very nice flat in a great location. Flat is clean, right on Passeig de Gracia, top floor and overlooking the roofs of Barcelona.

However, there have been some incidents. We had to wait over 30 minutes for a representative of our host showed up.
Then internet did not work properly which meant I could neither do any work nor organise our itinerary for Barcelona. On the 3rd day someone came to fix it, and for the last 2 days of our stay in worked very well.
The there was the issue of lingering sewage smell which came on and off and we could not figure out where it came from.

In the end its a mixed feeling. Great flat and location. Txcell was very reactive and did her best to sort the issues. Hopefully our problems were just one offs. If so then its a great place to stay
