Juan Carlos is a very welcoming and extremely helpful host.
On the day of arrival Juan Carlos was not in Madrid so organised for us to collect the keys from the cafe below the apartment. They were very friendly and helpful, so we popped back later for a cervaza and something to eat :-)
The apartment is small but had everything we needed for the two of us. Thank goodness for the air conditioning when you are in Madrid in July! The location is very close to the Lavapiies Metro, which is easy to get to if you are coming from the airport. It's also about a 15 - 20 minute walk to the Plaza da Mayor, but it's very easy to get to.
The street itself has big 24 hour supermarket about 2 mins walk and the supermarket has everything you need. There are plenty of cafes and restaurants right under the apartment and these add to the vibrant and life of the street that comes alive in the evening.
Juan Carlos stayed in regular contact with us throughout our stay, even joining us for a farewell drink on our last night.
This apartment is a must to stay in, especially with such an attentive and kind host.
