The location is terrible, not safe and away from the centre. The only way to get to the centre is by bus and until it arrives and takes you there you need at least 1 hour. The same applies on the way back.
The first night the outside door didn't work and there was no answer when we rang Vesta's bell. Finally an angry residence of the building opened the door for us. We were really scared because it's a creepy neighbourhood. Then the Vesta Residence key wouldn't open the door.
I;d rather have paid a bit more for a hostel near the centre.

Is not B AND B, is just bed!

There was only ONE bathroom for all the rooms (there was another one without lock, so nobady was using it). We had always some problems with the keys or the money... troobles that could avoid, in a first place.

The location is terrible. Dranks and gypsies all over the place. Has a metro station (tiburtina), but close at 22.00, so is imposible to go anywere or return from anywere. The only way to move is to take a bus to the center (that can be take hour to passby, throught the night).

The place is clean, but, the staff is horrible, specially the owner!!
they also won't help you with anything, specially directions... they hardly speak any english..

First of all, contrary to the name, Vesta is neither a hotel nor a B&B. It is simply a hostel with private rooms and a shared bathroom. (A private bathroom option is available, I think.) Staying at the Vesta can be a suitable experience if you intend just to sleep and shower. However, be prepared to take flip-flops to the shower (the bathroom floor gets very wet), pack lots of Kleenex (the bathroom frequently ran out of tissue), and pack some earplugs (at least two rooms are above a loud road that only dies down after midnight.) Other problems: broken shower head, cracked toilet lid, and the impression that the "fresh" towel placed in our towels everyday were just soiled towels from the previous night, refolded neatly.

On a positive note, the Vesta is very close to the Tiburtina metro stop, so we had no problems getting into the city. (Oh, the website states that it is near the Spanish Steps; it is nowhere near the Spanish Steps. Maybe four or five metro stops away.) The area appears very seedy (drunken loiterers and gypsies), but we never felt uncomfortable or felt that we were in danger.

It is also a very affordable place to stay, which I am sure is the only reason it gets business. Even if you book using a credit card, you must pay in cash for the entirety of your stay at check-in (this should be stated on your email confirmation.)
