We have been to Madrid quite a few times and especially love this neighbourhood, Lavapies.
Location is amazing and it’s a very quite building. The Airbnb is as advertised, small but spacious and very clean. Communication has room for improvement, you can request late check-out which we did. 12pm instead of 11am which is 1 hour difference… Got told they would check and reply, never heard anything back. Also no water or any other welcome gift upon arriving (previously we have got a bottle wine, some chips, orange juice,.. in other Airbnb’s.)
