German's flat is gorgeous and is just as pictured! My best friend and I had an enjoyable stay while there. As a host, German was very responsive and helpful as we navigated Madrid and the apartment!
The only issue during our stay was noise generated by construction going on in the apartment building. Hammering and drilling often woke us up around 9 or 10am (probably should have been up by then anyway lol) but it was annoying and inconvenient. This is not German's doing, of course, so I'm not sure he could have done much about it. Just ask if the building is still be upgrading when you book. Outside of that, our experience was great! Would certainly recommend the flat!
