Finding the apartment is very easy and is located near to several metro stops. Getting there from the airport is also very easy and Sito recommended exactly which lines to take which was also very helpful!
The apartment is cosy but was perfect for us as we were not staying in the apartment long during the days as we were exploring the city. Check in was easy with the girls who worked in the reception and they were very helpful in answering our questions, giving advice on what to explore in the city and helping us with anything in the apartment. The use of the roof top is also a nice touch and perfect for use when relaxing after walking around the city. You do need to buy anything in the apartment that you need such as sugar or salt etc and when you run out of bags for trash or toilet paper you also need to restock that and take the bins out- but as they say it is not a hotel and there are a lot of shops etc nearby so this wasn’t an issue!
Apartment is nice and cool and also quiet as it is located in a more residential area but within walking distance of a number of attractions such as parc guell and Sagrada Família :)
