The apartment in pleasant enough, the room is a bit small but everything is new and spotlessly clean. There is a private bathroom across the hall which is entirely modern.
Vereniz and Javi were friendly and we communicated as best we could. They thoughtfully always offered water, beer or wine when I arrived back from the July Madrid heat.
The bedroom dies get a bit stuffy with the heat but was bearable if the windows are opened wide in the evening and overnight. Noisy was not usually an issue.
All in all the listing provides a fine spot to bed down after exploring Madrid. It is central, well connected to the Metro, and is safe and pleasant.
