Alberto was very welcoming and ensured we could get hold of him if we needed to. The bijou apartment is very light and clean and there is almost no noise. It has everything you need for a short stay. The beds were very comfortable and the air conditioner in the small twin bedroom worked really well, necessary in the 34 degree heat of summer. The air conditioner on the mezzanine was struggling to cope with the big space it had to cool, but it was definitely cooler than outside. The 'terrace' is actually just a view from the top of the ladder in the small glass room next to the sitting room, one person at a time, but it was indeed spectacular. Of the two bedrooms, one is a mezzanine with a glass partition so there is no privacy from the sitting area if you are undressing/showering. There are a lot of sloping ceilings, notably over the loo, so anyone tall might find it interesting. I agree with a previous reviewer that it wouldn't be suitable for small children. The apartment is in a fantastic location, really central, a few minutes walk to the Metro and there are lots of good places to eat nearby. We can recommend Lizarran which is in the guest book, a chain that does very good montados, and La Buha, which does the best stuffed tortillas. I would definitely recommend it as a place for friends, or families with older children, to stay in Madrid.
