Had a recent business trip to Madrid and came across the El Madrono via a booking website.
First impressions were not great as the 'street appeal' on what looks like an urban side street gave us a little feeling of trepidation. The perception improved slightly when we entered the hotel as the reception was large and airy but very traditional in style with lots of dark wood and wall panels.
The staff member on reception was fantastic, making us feel instantly welcome. We stayed in a room on the 3rd floor accessed by rickety lifts and corridors where the lights come on as you walk down them and the bedroom door was painted an interesting shade of lilac!
The room however was cavernous consisting of a roomy ensuite with separate loo, albeit both had glass doors! The room opened out in to a very spacious lounge area wit sofas, coffee table etc and then the sleeping area. This had some interesting lighting and a semi reflective panel above the whole enormous bed. tasteful not kinky:) The bed was made up of 2 large single totalling some 8 feet from one side toe the other. Said goodnight to the wife and never saw or heard a thing from her until the morning.
In daylight we had the chance to look out of the floor to ceiling windows to see a delightful garden in the courtyard consisting of evergreen trees and shrubs and pathways.
Breakfast was good with the array of meats, cheeses, fruits, breads etc etc and lovely freshly pressed orange juice. Nothing hot available.
The location is not bad being apx half way between downtown Madrid and the airport and has good access to the Metro (apx 100 mtrs) and even the City Tour bus stop if you don't mind a good 10 - 15 minute walk.
The hotel does not serve evening meals but you can order a selection of food via room service where we were pleased to learn were reasonably priced. There a a number of restaurants within easy walking distance of the El Madrono and we became regulars for breakfast and dinner at the café at the end of the street.
We stayed for 3 nights and the excellent levels helpfulness and courteousness never dipped.
Give it a go
