Gulliermo's apartment it's fabulous. First, the place it's fantastic: it is in Lavapies barrio , next to the metro station (it's about 3 minutes walking ), which is just 1 stop from the city centre.
The house it's a wonderful place: all the house it's very new and lightning and there is the air conditioned in every room. The kitchen it's very complete: there is the oven, microonde and also electric cooker. there is the washing machine .
I stayed here for two weeks but I think that this could be a great solutions even if you have to spent few days in Madrid : there is everything you could desire!!
I didn't met Gulliermo but I met Elise a friend of him who has been very kindly with us : she explained me everything and she also suggested place to visit and stuff like this.
I'm trying but I'm not able to find a negative sign in this house !!! My valuation it's completely positive :D :D
If i ever come back in Madrid I will surely come to this apartment again :)
