Byron and Gerard are very attentive hosts and left us wine, chocolates and fruit for our arrival. There were lots of tourist guides and a handy map for our use. We slept peacefully as the flat faces an interior courtyard. The temperature was just right for us - it was early March. The bed was comfortable and it worked well having the mezzanine level. WiFi was very good here. I believe that any self catering would have been very difficult because of lack of space, but there really is no need to cook as so many bars are at your doorstep and food is so cheap in Spain. There is a huge 24hr supermarket 3 minutes away. Beware that the shower is super but only if you plan to be relatively quick. If the first person luxuriates then the water goes cold for the second... The flat does feel dark as it only has small windows overlooking the interior courtyard/ utiliity space.
Lavapies is an interesting part of Madrid that we had not explored before. It is extremely lively, full of young people and feels very genuine.
All in all, I would definitely recommend this studio for a short break, particularly suitable for people that plan to be out and about the majority of the time like we were.
