Celma and Gert were great hosts. The were very easy to contact, and always replied very fast. When we arrived at the airport, Gert told us how to get a taxi and when we got to the flat, Celma was there to get us and show us the flat. Celia does not speak English, but we could understand a but of Spanish, and Gert was on speakerphone the whole time, so he translated everything for us. The apartment is in the best possible location. Literally 2 minutes from Gran Via, the main shopping road. There is also a 24 hour cafe across the road and a 24 hour supermarket a few shops down. The flat is beautiful and you can tell it has been newly refurbished so everything was clean and pristine. The had coffee, extra towels, and best of all air conditioning...for those of you, like me, who are afraid of super hot afternoons! I have stayed in many places in Madrid and many didn't have good sound insulation because they had old windows, and you would be kept up all night by motorbikes, people shooting, garbage trucks, cars honking, etc. But they had great sound proofing so we heard minimal noise and had great night sleeps. 5 star place for a good price!
