Pablo's house is exactly as described and the pictures are accurate. This is a very comfortable house with a lovely homely feel.
The location was perfect for us as we didn't want to be in the busy city area. Yet everything is very accessible from the house.
Public transport (local bus) is 2 minutes away with metro a short walk. Parc Guell is only a few minutes walk and we also did longer walks to Placa Catalunya, passeig de Gracia (la Padrera and casa batillo), la Sagrada Familia, la rambla etc.
There are some small supermarkets, cafes and bars locally literally minutes from the door. Some local places don't stay open late at night but taxis are readily available to go further afield for dining etc.
The house itself is fully equipped with everything you could need for cooking (also coffee maker, juicer, kettle, toaster). The courtyard garden is lovely, unfortunately the weather wasn't great when we were there at end April and the garden was in shade for a lot of the day but it would be perfect in the summer time and we did still sit there with a coffee.
The house has both heating and air conditioning.
Pablo was a superb host who made himself available to us at all times. He was easy to contact and responded quickly. He also kindly allowed us to check in early on day of arrival. He gave us plenty of information and helpful tips for getting around. There are local transport details and maps in the house. As this was our first airbnb we weren't sure what to expect but we were pleased to find that towels and hairdryer were provided.
This was also our first time in Barcelona and we would definitely book Pablo's house again.
One thing, which didnt affect us, but just to bear in mind is that the area is at the top of steep hill and there are some steps up to the house.
