Check-in is after 4pm, but then we didn't read in the description that there is a penalty of 10 euros if you arrive after 8pm - that seems like a pretty small window to me to check-in without being penalised...Never found that before on Air BnB. Thankfully we were able to get there for 7.55pm!
Place is smaller than we expected. Bed is a foldup one from the wall. Having said that, the best thing about the apartment was the bed! It was really comfy so no worries there at all. Once it is down though, it is difficult to get around such a small space. Lighting needs sorting out. A small table lamp would be good to use at night time or when getting up. There's not much natural light, but as it is you have to only switch on two interrogation-strength fluorescent lights and it's already too bright. With the black and white decor it felt like we were in a crossword. No nice touches like a bit of shower gel, soap, coffee or other things which cost practically nothing but make so much difference for guests. Plenty of stern warnings about your conduct when you are in there however, all making it feel a bit military.
There were a couple of problems with the apartment, which I've pointed out to the owner and presume he will sort out. For the extra ten euros you can rent out something substantially bigger and that's what I'll do next time.
Location is great. Right in the heart of Chueca and lots of life. Everything you need nearby and more.
