We loved our stay in Gemma&Alex' apartment. The location was GREAT to a lot of Gaudi places and the metro just a minute away. From here you can reach all places within just a couple of stations. The T 10 Ticket is very cheap way of exploring the city. The apartment is absolutely quiet; you don't hear any noise from the road. The beds are very comfortable. The kitchen was well equipped.
We can recommend it definitely and would book it again.
