Martin`s place is an absolutely amazing place to stay in when visiting Madrid. Really easy to get to from the airport and close to the metro/bus stations (for example if you are visiting Madrid Mutua Open and want to get to the tennis courts, then it is easy to get there from the apartment with the metro). The apartment was nice and clean - everything was there, what we needed and we got tips about where to go and what to see in Madrid as well. Wifi was excellent as well. We managed to go around by foot - all the main sights are just a walk away and near the apartment is a nice park where to have a picnic or just to sit down on a grass and enjoy the warm breeze and evening sun. The neighbourhood is good - nothing to be scared about when walking around the streets in the night time. People are friendly and nice. Just keep a look out on your personal items as you do regularly :). 10/10 - would definitely book this apartment again when in Madrid.
