My friend and I had a lovely few days at Charlie and Edu's. The room was bright and clean, with a very nice small balcony. The bed was comfortable and there was enough storage room etc. The shower was hot, although the shower curtain was sometimes a bit ineffective!
Charlie was very welcoming and made us feel at home. The kitchen was great - a very nice space, with storage space in the fridge.
There was a general feeling of generosity which made our time at Charlie and Edu's memorable. There was a lovely sharing system of use and replace of the basic food (oil, tea, cereals) which was a great idea that worked really well. If we come back to Madrid, we'll be sure to come back!! Gracias!
