Laura was very flexible - we didn't get to hers until 11.40pm and she was there waiting for us with a smile. The place was compact but clean and tidy, she had scented candles burning which made the place smell lovely. We had not been to Madrid before so I wasn't sure about the street as many of the shop shutters were covered in graffiti, however the next few days we realised how central the apartment was - a short walk to Plaza Major - Opera etc so it was very convenient. We picked a weekend where it did not stop raining, so it was great to come back to a flat that was always warm. Another plus for my boyfriend in particular was the electric blinds on all the windows which gave the room a total blackout - great for sleeping in after a late Madrid dinner! There was some traffic noise on the Monday morning but I didn't notice it on the weekends - the price you pay for being so central and certainly worth it - take some ear plugs if you're sensitive. The wifi worked pretty well and Laura was also flexible at check out time - and booked us a taxi - great service!
