Nacho's flat was quite comfortable and had everything you would need for your stay in Sevilla. I was greeted by his sister who was delightful. The flat is close to many shops, a supermarket, pharmacy, restaurants, and 4 beautiful churches. The cathedral is about a 25 minute walk. The bus station is about 5 minutes away and taxis are plentiful.
The only 2 negatives is that the interior of the building is going through some renovations so it is not asthetically pleasing to the eye and at times it's noisy and dusty. The other negative is that it's on the 2nd floor with no lift and tight winding staircases so anyone with leg or knee issues will definitely have a problem. Luckily, his sister was able to assist with my suitcase and bag which were quite heavy.
I would DEFINITELY recommend Nacho's flat because once inside I was quite satisfied, comfortable and pleased with the location.
Thank you Nacho. It was a pleasure.
