I stayed 8 days in Albert house, and I can say it was amazing. First of all, the apartment is very beautiful, full of light, and it is closer to the metro than I expected. Then, the dogs are adorable, and they are not noisy at all. Albert and Rafa are very nice, they are not often in the apartment so it is sometime a private flat that you are taking :p
One last thing: I had a friend coming in the weekend, and they had absolutely no problem, which was very cool from them. I totally would advise this flat, thanks guys!
