This apartment is absolutely gorgeous and very comfortable with lots of seating in the living room, 3 King-sized beds that can be converted to twins (we had to do this ourselves but it was easy), and a great location. We walked to Puerto de Sol and up and down Gran Via. There are many good restaraunts and a grocery store/food court nearby as well as lots of shopping (especially shoe stores!) The only downside was a lot of street noise at night in two of the bedrooms. The middle-sized room was quiet thanks to a double glassed balcony and some good ear plugs took care of those in the other two rooms.
Pablo was a wonderful host! He texted a couple of times to be sure we were doing ok and even brought us a US-style coffee maker when he found out we weren't espresso drinkers. The neighbors were very friendly and offered lots of tips on the city and neighborhood.
We are a group of experienced travelers and this was one of the nicest apartments we haved stayed in! Thanks, Pablo!
