I stayed at Carlos & Frank A+ Apartments with my wife and young daughter for ten days.
We had a wonderful time in Madrid and Carlos was most kind in explaining how to get around the city. The apartment was in very good condition, the bed comfortable and the shower was excellent. The wifi internet connection was fast which is always important when you’re traveling so you can stay in touch with everyone. Thanks to Carlos (didn’t meet Frank) we had a great time in Madrid!!!
