Our accomodation in Ruty's and Dennis' appartment between Gran Vía and Puertae del sol has been a very good basis for our stay in Madrid. The location probably can't be better in case you want to discover the heart of Madrid but be as flexible as much in travelling to others spots in Madrid or places around. One thing that was a pity was that Gran Vía Metro station is currently closed due to working. But that's nothing that is up to the hosts, of course. Furthermore, Sol, for example, is very close, too.
Besides the location the appartment was clean and tidy. Most things you are going to need are available. Some things we would have wishes moreover are: more toilet paper (two rolls for two persons a week is not too much), one or two more towels and perhaps some washing powder for the machine.
It is not too large actually but absolutely sufficient for a holiday. The bathroom is very small but okay. The equipment is nice and lovely.
When we arrived the cleaning girl had forgotten to leave the safe lock at the door, so we couldn't enter the appartment. Though, Ruty was there 20 minutes later with the keys and very friendly and kind. We have to admit that we had agreed in handing out the keys in person but our flight was three hours late so probably the misunderstanding was caused by that.
We can absolutely recommend the appartment if you don't mind climbing to the fourth floor.
