The appartement was pretty and spacious enough for a family of 5. The appartment was clean, hotel type of clean.
When we arrived the appartment wasn't ready so we had to go outside and wait a little over an hour before accessing the premise.
The wifi wasn't reliable. Thankfully there is wifi in almost every corner of Barcelona.
The appartment is well located, walking distance from Sagrada Familia and main metro line. There is plenty of little restaurants on the street. You don't have to go far to find what you need. It was accessible.
The appartment building itself is very noisy. The cleaning crew comes very early and make plenty of noise. There is a lot circulation of people coming and going and that at any time. If you are a light sleeper it may not be a good fit.
Overall we enjoyed our stay and enjoyed the experience.
