Great duplex one bed fourth floor apartment with views out to the square.
Expect some of the usual caveats of an old building in a European city :
- retro fit small elevator to the floor
- shape, fittings and fixtures of apartment and building
There is a certain noise level at the weekend you should be aware of due to the location. Plaza de Callao can get very busy over the weekends and public holidays, and there are lights on billboards which do affect sleep etc in the apartment should this be a potential issue for you. We were generally pretty tired (and wine / vermouth filled) for this to have much of an impact.
The wooden spiral stairs in the apartment is not very suitable for people with mobility issues as some of the steps are not level, and I would not recommend this apartment for young children due to the stairs and balconies.
Only other small issue is that the downstairs toilet could use a bit of work.
Communication from Alicia was excellent,with punctual meetings and quick replies. Also gave us tips on luggage storage which was great.
In an excellent location if the above is ok with you! Really great spot to get around from, with minimal metro use needed. Walking distance to most central spots, opposite an el cortex ingles supermarket and along grand via which is the main shopping street.
