Got a chance to meet both Carlos and Alba who also lives in the same building. Alba was very friendly and helpful throughout the 7 nights stay.

The place was modern and clean which was very imprtant to us. It was also very conveniently located as its a very comfortable walking distance (5mins) to the airport metro and city metro. The place is comfortable for two but they also have another apartment for larger group. Wifi was also strong. Enough kitchen utensils for basic cooking. The apartment also has washing machine but you will need to bring your own detergent. Thats not an issue as there are alot of supermarkets nearby.

The only con i would mention is the soundproofing which I suspect alot of the apartments in spain are similar. We had a neighbour who was disturbed with our footsteps and even banged the wall. That made us very conscious of our movements and it almost felt restrictive. Little did they know that we could also hear their footsteps and noise at 3.30am in the morning. That said, it was bearable for us and so we did not make a fuss of it. Generally, the level of sound was reasonable as long as it's not past bedtime.

All in all, we would highly recommend Alba's place as it's truly convenient, comfortable and reasonably priced! Oh forgot to mention, we were also treated with rounds of fireworks that could be enjoyed from the apartment. Beautiful place!
