The place is convenient, Malasaña is just on
Your doorstep.
You might need to phone the host to ask him to bring some missing stuff, lamp on the sitting room doesn’t work, no drinking glasses, ...but it is not a big deal. However, make sure you don’t forget any thing worth when you leave. You won’t have a chance to get it back even if you phone straight away!! They will dispose of it as soon as you leave even if it is dear.
