Esther was SUPER nice and accommodating. She was very helpful during check in/out and also provided many tips on things to see and do around town. She went above and beyond as a host :) Definitely would stay here again! The flat is cozy and although it's on a somewhat busy street (pedestrians), it's very quiet because of it's location on the inside of the building. It's also super central and there's an abundance of shops, restaurants, bars, etc. Anything and everything you need is just around the corner. The neighborhood is very safe so there was never any problem walking home at the end of the night. The flat is located near the metro station and was an easy connection to the airport. Looking forward to my next trip to Madrid!
