A comfortable base in a great central location in Madrid. The flat is as shown in the pictures, compact and sparsely furnished, but comfortable and with good quality fittings. Generally quiet (only some distant street noise) despite being very central.
I did have an issue with the internet connection, which was very unstable the first day, and it turned out that it was shared with another flat (which was where the router was). I had to get a local sim card to get reliable internet access, and although in the end wifi seemed to work ok please keep this in mind if you need good wifi eg for work (as I did)
