Isaac's place is perfectly located in the Rustafa neighborhood. It is central, close to Carrer de Buenos Aires, but still in a place where you don't get any noise at all from all the restaurants and bars in Rustafa. At the same time you are literally 5 min walk from hundreds of places to eat or drink. There's also a Consum only a few hundred yards away for those who prefer to eat at home.
The apartment is great for a couple or a family. Spacious living room and a good sized bathroom. Bedroom with king size bed and a small kitchen with everything you need. The place is modern and very stylish.
As a host Isaac is close to perfect. Super friendly, easy to communicate with and eager to make your stay great. He will make sure nothing goes wrong while you're there.
The only important note about this apartment is that it's on the top floor of the building. Positive side of this is that there is no noise from neighbors and you have good views of the surrounding area. Depending on who you are the downside is that you get to exercise your legs.
